While I agree that it's hard to support legislation that's likely to have a lot of unintended consequences, it's also important to realize what's driving folks to introduce a bill like this. It's also worth pointing out that (in particular with Netflix) your example is its own counter-argument. You can't turn off autoplay, and that's the opposite of letting me make choices for myself.

There's also plenty of other examples of government regulating or banning things which exploit human weakness. Ponzi schemes, meth, gambling, and more are all controlled. It's pretty clear that a lot of tech-company design is (intentionally or not) probably scratching a lot of the same itches. It's reasonable to expect regulation.
