The problem with those tweets that you've liked is that they're misinformation. They may sound reasonable on the surface but what they're saying is factually wrong. Make sure to fact check any statements you read on Twitter, going with the most plausible-feeling explanation is a form of bias.

Now I don't think that excuses other bad behavior from GNOME developers. If they're saying rude and demeaning things while representing themselves as a GNOME developer then those should be reported to the code of conduct committee, even if they're on Twitter.
