This is pure dramaposting- "post-mortem" is so misleading and mischaracterizes the situation. I don't use bazzite, I don't know Kyle or anybody here, but I am tired of the drama.
All of the things listed in the blog are personal and technical disagreements, nothing morally reprehensible, no disrespect, nothing that would make anyone want to burn bridges like this.
It's fine to leave a project and to publicize disagreements but this comes across as spiteful.
