I wished more people would take issue with developers' bad attitudes.
I know this is an extremely unpopular take, but I refuse to use software where the main dev(s) are openly abusive to others. Sadly this includes the majority of open source operating systems and many other very popular applications... but it's my decision and you're welcome to disagree with me. I am not trying to prevent others from using said software, and I don't look down on them for it.
I think if everyone was always forced to separate the art from the artist, then boycotting wouldn't even be a thing, so there should probably be some kind of middle ground.
