If every single mobile network plan is legally required to support Netflix 4K and YouTube streaming, that's not workable from a business standpoint. And that's exactly Google and Netflix's goal: Require everything support their modern reincarnation of the boob tube.
I feel a very small group of companies are pushing an incredibly wasteful business model, because they aren't the ones paying for all of the waste. Google, Netflix, Spotify, etc. would rather you wirelessly stream content that makes... a lot more sense to store locally. And they're pushing things like streaming 4K... even when the cost/benefit of streaming 4K to a phone is questionable at best.
We're all paying for the extreme network contention of 90% of available bandwidth going to these very wasteful business models. It's pretty unsurprising ISPs would like to charge extra for them, either towards consumers or the streaming providers themselves.
I haven't noticed that - I have noticed opposition to other anti-consumer business practices, like inaccurately calling a plan "unlimited data", or pushing low-income people into capped data plans and charging excessive per-GB overage fees. I think a plan like you're suggesting is perfectly compatible with net neutrality goals - I just think there's not much of a market. But Google Fi is pretty close - as in not throttled and constant per-GB prices, and you can get extra sim cards for free for your other devices.
> Notice that "unlimited data" is once again, however inaccurate as it is, nearly the only way to buy wireless service in 2020.
Note that this is not the case in situations where bandwidth is actually scarce, such as satellite internet plans.
I think you're saying that these businesses have externalized the cost of bandwidth to consumers. I agree that ISPs charge a ridiculous amount, but are you sure this is actually the reason? I would have assumed it's more due to the lack of alternative providers that most in the US face.
As to reasons on why to not enforce net neutrality strictly is that it stifles investment in ISPs infrastructure.
