I'm not a developer either, so take this as an observer's speculation.
My impression is that venture capitalists took a long look at the fediverse and chucked their money at Bluesky instead, because it actually works more similar to "ye olde" social networks — specifically with a business plan, road map and traditional organisational structure.
The parts of the fediverse that I am most inclined toward is too unruly, recalcitrant and noncommercial to attract deeper interest from VC investors. They are deliberately built and organised to resist expectancy of capital return on investments.
So my conclusion is the reverse of what you'd rather not discuss — in my eyes, the fediverse isn't very good for investors, because until now it's largely been grassrootsy. It will be interesting to see what VC-friendly platforms emerges in the vein of Bluesky or even Threads, and to what degree they will overlap with the current fediverse.
