It is about time that corporations, with GitHub here as an example, noticed that backing this or that or another minority or "trying" to solve some medial issue only where it suits them PR-wise is simply abusing that minority in yet another way; it is a means of using that minority, and all the people who constitute that minority, as a tool for public relation stunts and political "but we support X, see?" newspeak that brings no actual change.
I'm genuinely curious if GitHub does support Black and Brown people enough to actually make that support noticeable for everyday lives of these folk.
For example, at an individual level, there is a lot of good research about how housing segregation is one of the largest continuing drivers in systemic racism in the US. So if you have a bunch of BLM posters in your yard, but at the same time fight tooth-and-nail against any increased density in your neighborhood that might actually lower housing costs where you live, well you should just STFU, or at least realize the underpinnings of your blatant hypocrisy.
Could you link some of it? I'm alien to this particular issue.
