I don't even know what to make of that anymore. Just because it's self-deprecating doesn't make it okay.
I mean the tweet is putting the blame at the wrong people (it's a business decision after all), but I wouldn't go as far as call it "hate-inciting nonsense". You're not under attack.
I don't see it.
An appliance going "nope, I have one path for this" is, tbh, to be expected. A dishwasher washes dishes, and the idea that there is a secret-sauce way to tell it to do something it isn't actively presenting to you is not something a reasonable person is going to expect. It's why my dishwasher has like eight buttons on the top--it enumerates everything it can do. So if that appliance is hiding its verbs, then a reasonable person is going to assume it doesn't have any.
It would be best if most machines didn't talk to us, at all. Press a button: it runs. Nothing more.
I can't think of a good reason to have a network-connected dishwasher. I don't think I'd ever start it remotely, as I still have to clear the table and rinse the dishes. The washer gets started when I'm done loading it. I can check detergent levels while the door is open.
Pretty much the same for all my other appliance for that matter.
I did see the twitter screenshots, but as I don't own the device myself I couldn't really judge if the GP's instructions are readily apparent to the average user.
Also, I don't disagree with you. But the OP seemingly bought such a device and connected it to their wifi. Maybe they are living in a furnished apartment with pre-configured wifi? Anyway - thankfully we are not yet in an era where ones only choice is a connected dishwasher - can still buy used, older models etc.
edit: One would hope that you can factory reset the dishwasher to make it forget the wifi information, if it has been configured by someone else.
