You might be interested in digging into the IndieWeb — a loose but large community of people knit together on a variety of platforms, usually self-hosted, including micro.blog and WordPress. Their call-to-action is very similar to what you’re writing (freedom from Big Social) along with some other ideas, such as a return to the more creative, free-wheeling internet of the 90s. It was completely off my radar until I stumbled across some good content that just happened to be by an IndieWeb blogger. There’s more about it on Wikipedia and this .org site.
