I thought this was the case but here is the founder of skylight saying it. Developers using #ATproto not only get access to their larger network, but they also have #bluesky paying for most if not all their infrastructure costs. So of course they are building there instead of here. And over time, the VC money also means they can outlast anything built on fedi.
The whole #ATmosphere is becoming dependent on the company itself and VC money.
