Pressing Bake turns the oven on after a random delay, if you didn't press Bake the oven wouldn't turn on at all. Ergo you turned the oven on, no matter how much you lawyer speak your way around it.
Just reinforces how ludicrous the meaningless rules are, that surround all religions.
Which is by the by to the point -- if the rules are there, the amount of effort spent to creatively discount them feels like nothing other than blatant cheating. A sleight of hand.
Note also my response to your second comment to my original -- OP said nothing of it needing to be used before the sabbath. In terms of the eruv, what may be a gentle convenience or exception for a few neighbouring houses, or relations, seems to really stretch when it encompasses tens of thousands+ in multiple city regions. Though I note from other comments regarding Feinsten, if accurate, that some noted Jewish scholars appear to have thought the concept stretched the point too.
I am not an eruv or even a Jewish law expert, but I can assure you though that Rabbi Moshe Feinsteins positions were widely accepted in the Orthodox Community and his opinions are not only well documented and sourced, they are studied today much like court precedents are set. There are obviously differing view points, but in order to disagree with him and be listened to, one would need to extensively show their math and support their dissenting opinion with reliable sources and case history...
In general, the rule of thumb around Jewish law atleast for Orthodox Jews is, "ask your local orthodox rabbi." And interestingly enough, when interviewing for synagogue and pulpit positions, one of the common questions asked of Rabbi Applicants is "who do you ask your religious and halachik questions to?" Central to the faith is collaboration and discussion at the highest levels and if you arent stumped constantly and discussing with mentors and peers, you by default disqualify your credentials to most Ultra Orthodx Jews.
Religion is an exploit of faith to allow power to beget more power, just like any other "isms" like capitalism, fascism, socialism, etc etc.
I wont pretend to understand consciousness or the human experience...but I like to be pragmatic, and from a pragmatic perspective, I dont see the utility of your belief about religion and faith and power structures...its an almost helpleas viewpoint that rejects everything as imaginary and malleable...and I dont see the value in that in my own beliefs and philosophy.
So now I'm not sure how to interpret.
As difficult as it may seem to many people, the "hacks" are grounded in sound but nuanced reasoning...the cases that make no sense logically are typically mistaken application...the talmud is literally rabbis disproving these ideas based on logic all the time.
The name is a misnomer because the baking function can only be used on Jewish holidays (Passover, Sukkot) when baking/cooking is permitted (okhel nefesh) whereas on Sabbath cooking is forbidden.
Rather, sabbath mode is things like... a sabbath mode elevator just goes up and down all day stopping at every floor, so nobody needs to press any call or floor buttons. A sabbath mode oven, what it actually does, it just stay on all day (disabling features that will turn it off if unattended for a few hours), so you can just leave it on at a relatively low temperature all day and put things in and out of it, without starting a fire yourself. (It is starting the fire that is forbidden not making use of it). (In some cases a timer you set in advance before the sabbath is okay though, so perhaps a sabbath mode oven could have a timer you set Friday afternoon telling it to turn on and/or off at some point in the future).
HOWEVER. In general. I think there is a larger point. As someone who does not particularly believe in God, but still has some respect for following disciplines like this: You say the rules are "meaningless" -- but I would say the rules are meaningful only because of the meaning WE give them, the effect they have on us, the meaning we find in them.
If you don't believe in God, that's the only kind of meaning there is, anyway, right? Or you believe everything is meaningless in a kind of nihilism, which is something some people do, but I don't believe it's what most of us atheists do or is the only option.
So the rules of shabbat can be "meaningful" because of the meaning we find in them, because of the _experience_ of following them, which may be an experience that we find meaningful, especially when done with a community doing it consistently. Shabbat is a good example, because I find it to be so, having some experience with observing it in a community; it is a pleasurable and personally meaningful experience with no need to believe in God to make it so. So whether a modification of a 'strict' rule would make sense would depend as much on the effects it has on the practice as anything else.
I don't think religious Jews usually look at it quite this way (although not as different as you may think either); but the Amish, for instance, I think are closer to this. It's not exactly that God said don't use cars so you go to hell if you use a car; it's what effect do cars have on our lives and communities, and do we want those effects, and it might be okay to use a car sometimes in ways that minimize those effects for a greater good (say, an ambulance, perhaps).
As they become no longer of their time, it becomes the rule that is significant and the heritage, and becomes the heritage rather than the reason it might have been instituted way back when. Yet just about every society develops habits and rituals. Occasionally they turn out to be counter-productive to the adherents in a modern world. Now you certainly raise a good point about the experience of following -- the ritual itself can take on importance, and the community benefits are well known. Decline of community appears to be implicated in no end of modern problems, and whether secular or religious, anything that preserves it is to be lauded.
I'm surprised at the discussion spun up from the oven feature -- seems like some manufacturers may interpret the feature differently to others. Which is correct, and which right for Judaism, I'm unqualified to say. A sabbath mode elevator is, to my mind, a much more obvious and clean workaround that seems to preserve the spirit of the underlying idea.
As an atheist with Jewish background who is thinking more about Jewish traditions these days, some thoughts are: The act of figuring out as a community the details of the rules (or 'exceptions' of they seem so) in the face of changing social conditions can itself be meaningful. It can produce meaning related to bringing people into a community of discussion and debate in which decisions are made, or of authoritarian following the orders of a designated leader who decides how you are to interpret the rules, or some combination thereof.
It's all full of meaning, very meaning-producing. It may be intentional or unintentional, the kind of meaning we'd want or not want. Once you are an atheist -- or otherwise don't believe that there is a God who speaks to us in human language giving commands -- it actually frees you (singular or plural) up to alter the practices to produce the meaning you want.
As an atheist of Protestant heritage I've wondered on the secret sauce of religion that brings the obviously stronger sense of community, as it appears to run deeper than faith, and whether there are ways to achieve that in a secular context. Perhaps particularly difficult in an era when individual choice and consumerism is promoted as paramount. :)
But Jewish practice generally/traditionally is really big on "community" as a focus and priority, and religiously observant Jews would agree that's so, in general, I think. They would of course probably say that the reason they do things the way they do, though, is because God said so, the end.
But as outside "sociologists" or "anthropologists" we can have our own interpretations, although perhaps it's rude.
But then, for some interesting additional anthropology, I know increasing numbers of atheist/agnostic Jews, not from Orthodox communities, who I think have attitudes toward Jewish practice along the lines we are talking about...
You can read about typical sabbath mode's on ovens, as well as other appliances, on wikipedia, which also has some info about how much consensus there is about the legality of various approaches.
https://en.wikipedia.org/wiki/Sabbath_mode#Oven
For ovens, it does indeed say "With some Shabbat mode ovens that are controlled using a keypad to set the temperature, there is a random delay triggered after a button is pressed before the temperature change takes place", but after going over other more common "sabbath modes" on ovens.
