The problem is we can't just not use their internet - I see extending the fediverse as a great way to bring back the original promise of the Internet, a free place for collaboration and exchange of ideas.

But we still need to use the normal Internet for daily life. The potential control here goes so far past ad blocking or browser choice - what happens when they start deciding what apps you can have, or what os, or if your using an unmodified locked down system without root access?

Plus, you have legislation like kosa that could be used to restrict people from operating websites locally in the US.

This move alone wouldn't kill the Internet, but you have to look at the wider context. This is an inflection point - tech giants are on an all out money grab, and a lot of important battles are going to happen back to back. Losing any one of them will be just an inconvenience, but all together they're going to redefine the rules moving forward
