I think he’s literally talking about investing in fediverse companies, which I guess isn’t really any better.

I haven’t used it but there’s ProxiTok.

That’s at a very different level. With dot social it’s about a quarter of the active users on the fediverse, whereas bluesky is probably something like 95% centralized in practice. It seems to keep improving, but right now it’s basically impossible to use without mostly interacting with bsky.
