Changing behaviour is very hard. You'd have to get people to install new apps, get use to new workflows etc and humans are creatures of habit so this is very hard.
I think this is pretty optimistic thinking. "Oh no, I can't pick my way through a bunch of bigoted garbage to which the owner responds 'Concerning' or read Marc Andreesen being deeply weird or see 30,000 reply guys to Paul Graham hawking shitcoins, whatever will I do?" is, I think, probably okay at this point.
Having the thinkfluencey types before the spam and impersonation taps were turned on to full was probably valuable; now Twitter is getting the stink on it and that's hard to wash off.
Personally speaking, Bluesky picked up pretty much everybody I care to talk to and remaining on Twitter in a material capacity is a flag that I probably don't want to hear from you.
The conversation was about X being built from the ground up and attracting new users which is much harder.
BlueSky only started gaining traction after Musk started pissing people off, doubt prag would have done the same.
The non-technical tech sphere hasn't really moved though, but maybe my circles are quite different to yours.
(The dynamic is very different when it's voluntary and feels like supporting a community, though, and in practice it's going to be a few whales making donations)
Not everything has to be about making money, you realise.
That's not really how it works. Federation happens ~by default in general; restriction is reactive, not proactive.
But you still breathe, right?
Why pay (as much) to advertise to an empt(ier) room?
