Yup - I like the fediverse too, but I have plenty of clients who don't. Plenty tried Bluesky, most have left. They all seem to be going towards (shudder) threads now
I'm not afraid of that at all. But if you draw shit tons of power from a crappy socket, things start to heat up real quick. Like getting really fucking hot, as in burn your house down hot.
Divide and conquer. Non state-actors and special interest have a far easier time attacking a hundred small entities than one big one. Because people have much less bandwidth to track all this shit than it is to spread it around. See ALEC and the strategy behind state rights.
In the end this is about economic power. The only way to curb it is through a democratic government. Lemmy servers too can be bought and sold and the communities captured that grew on them.
