I’ve been intrigued by this, the only source I’ve seen about the Lemmy devs being tankies is one user posting on Mastodon that they reported quite pretty despicable tankie comments on that instance, and the Lemmy devs (who also admin the instance) refused to take them down. Which I would get and I don’t think it makes them agree with the comments, in the “I disapprove of what you say but I will fight to the death your right to say it” kinda way.
Was there anything else? This is the first I hear of them actually removing content.
