How do I put this? If this is how you respond to criticism, and that's what you've clearly shown repeatedly to do, then you should not be in any leadership position.
You do not apologize even when you admit to be wrong, you blame others instead of taking responsibilities for anything that was said here. It's entirely a dismissive response. You might not have noticed but people do not feel valued at all when they speak to Lemmy's developers. Their input is dismissed, they are told to make issues that you do not care for and when they ask for something to be better prioritized, you effectively tell them to fuck off. You make people feel that their time and effort towards Lemmy is worthless.
With the way you've acted, you have pushed back people from making issues, from contributing in code or otherwise, from wanting to host Lemmy and wanting to be associated with the project. Sincerely, all I can hope at this point is for Lemmy to be forked by better people or to be forgotten about.
