From reading the linked post-mortem written by Antheas (the one that was kicked out for CoC violations) It sounds to me like there are multiple people acting unprofessionally in this situation.

Of course it’s hard to tell when you only have one side of the story, and it was written by the one who was kicked out, but without a rebuttal from the other team member mentioned, it sounds like childish politics and unprofessional development practise all around.

I would hope that with the attention that Bazzite is getting it should get an injection of contributors who hopefully are more mature in their interactions with other community members.
