I never said there was. I'd prefer it if they made AP better instead. And there's a lot of room for improvement.

Well, there are many different aspects to take into account. I was thinking more of how inefficient AP is when it comes to system resources and network usage, and some other things I can't remember that made me go "yikes" when I read it. Also how it's used for things the protocol doesn't really have support for, so devs make their own solutions that are now part of the AP Fediverse even though the protocol itself, that is the backbone of the thing in question, doesn't support the things that is a part of the thing. It seems a big mess in many ways, and I believe that Bluesky doesn't have those issues.

They're still for profit and corporate leadership and values can change. I wouldn't trust it.

Yup. PBC is just a slightly different flavor of a standard corporation. Bluesky have investors, they're burning investor money right now, they don't know how to monetize the platform yet, and when those investors come knocking for their ROI it's the same ol enshittification process all over again. No thanks. I don't care if the backend is FOSS as long as it all revolves around a corporation, especially one with the roots of Bluesky. If there grows a viable and open community and ecosystem out of that, completely self-sustaining without the need for the corporation, using the FOSS code (or perhaps preferably a fork of it), then that's a different story and that could be interesting.

That's how OpenAI used to describe themselves, too.
