it’s bad. he will steamroll the fediverse, make everyone want to go to his platform (“look at the features we have that they don’t! its ok tho, we still federate with them, so come here!”) and once he gets the majority of people there, which he honestly already has, he will defederate from everyone. he will once again go back to being a centralized platform, killing a large portion of the fediverse along with it.
