I think it's half moderators on strike, and half people acting disrespectfully because they have no respect for Reddit since Reddit showed them they have no respect for them. When the platform is run by a malicious faceless corporation there's less of a feeling of obligation to be civil, but on Lemmy these instances are being run by volunteers and when I see the hard work they're putting in to keep things running it makes me respect them and it feels more like an actual community that I want to treat well.
