i wonder if we will end using personal webpages with FOSS/affordable domains and integration to forums and video platforms, just to avoid some crazy CEO screwing our content again.

That's what we had before. And it never stopped to exist, it just dwindled out for convenience.

• no more personal website but just a "facebook page", for convenience
• no integration between sites, just a few huge ones, for convenience
• no customisation and personal expression but large, uniformised experience, for convenience
• no small hosting and individual presence online, just a few massive (corporate) infrastructures graciously given to us, for convenience
• no control over policies and content, just be happy with what our generous overlord allows us to do, for convenience

The "fediverse" is a step in the good direction, but as long as the general user don't care, these huge services will keep being the "main" internet for the forseeable future. Even abusing the userbase and getting batshit crazy with rules and restrictions isn't stopping them.

Meanwhile, some of us are happy on out littler corner of the internet, using RSS to see what's new on individual websites, and depending on services that are either sanely hosted or even self-hosted and interoperable. But that's not for everyone.
