For the sake of Lemmy’s growth, it’s problematic that join-lemmy.org (as an official platform) features Hexbear, Lemmygrad, and Lemmy.ml so prominently. While I dislike Reddit enough to have not tossed away Lemmy as a whole for its tankies and instead blocked those instances, featuring and recommending the use of extremist instances hurts Lemmy’s image (and Piefed and Mbin by association) in the eyes of potential users.

Speak for yourself, the fact that Lemmy offers leftist and communist instances is a big draw for a lot of users, myself included. They are prominent due to their size and activity, and recommending them for those who want them is good for growth. Further, for those that prefer not to be on leftist/communist instances, it’s good that the communists have a place to go to, rather than joining, say, Lemmy.world, which would be a poor fit and result in far more friction.
