Its distant memories now, but there was a time that they did a lot to make left leaning ideology look good, likely setting back the movement.
For example they mentioned publicly that “its hard to even interview a white male” and that “white women are the biggest barriers to [progressive policies] in tech”.
There was also the whole kerfuffle with badgering repo maintainers to remove words such as blacklist, and (very minorly) the push for main instead of master (and the understandable frustration to everyone not bothering with identity politics).
Honestly, I was following it at the time and I was greatly irritated at the time, now I’m just tired of it all and refuse to engage with the topic in any way. I can understand why others feel the same.
Github has not done anything irritating in quite some time though, so its moot in my opinion.
I think I've seen main instead of master, but I don't even recall that being a political issue. Although, I'm biased by my empiricism which means I generally only keep track of actual policy rather than "culture war" issues.
