Some interesting points, and some things I disagree with.
Firstly it's annoying he keeps calling it his idea and trying to enforce this concept that the current internet needs to align with his original goals. That's stupid and ignores that things will go where they go, he can't control them.
So his first point about centralisation being an issue isn't that big a grievance. But his second point rings true - the issues around our data and advertising have grown significantly and the Web is getting much worse as a result.
I actually think the solution is just government needs to step in and regulate it, along the lines of what the EU is doing. Realistically I think that's the only solution that'll help. Doing some grassroots movement and hoping it picks up steam is just unrealistic. Like looking at Lemmy and Mastadon - they're great but at this pace they'll never take over the other giants in the space. You need someone to step in and force the change.
