The key point here is not that they think you’re stupid but that they refuse to let you say no.
One of the Google founders (Sergei I think) read the book “nudge” and fell in love with it. What Google product managers fail to realize is that a hard nudge is called a shove. And removing the ability to say no is theft of consent. They continue to do it because it works and there’s nobody left there with enough courage to stop them.

I'd add it's also that there's nobody left to compete with them, either. They own the only desktop browser that matters, and basically the entire concept of the mobile phone itself outside the US (Android), and it seems like 50% or so of the corporate email market, 80% of the consumer email market, a high percentage of the advertising market. I don't think pre-1984 AT&T had half the dominance Google does.
