To be fair to them, they have done a significant amount of work to design the network to be open to competing servers, and I think it would be quite tricky to unpick that. In comparison to successful networks like TikTok, Twitter, Facebook, LinkedIn, ATP gives a far fairer playing field and Bluesky hasn't done anything (aside from taking funding) to suggest they're not going to run with it.
You are right that they could change their architecture so that their Relay is more trusted or blocks others in some way, once they capture the market. I am not sure what guarantee they could give with the current ATP arch - perhaps a committee would help, but other social networks have no incentive to support ATP.
