>The real question is: is a repo purge going to follow from their internal purge? Will they start deleting projects with diverging political views?

They've already done that. https://github.com/FeministSoftwareFoundation/C-plus-Equalit...

However, they continue to host a mirror of it: https://github.com/ErisBlastar/cplusequality

Not sure why they didn't allow the "official" one but allow the mirror. Guess they just wanted the ability to say they took it down for PR purposes.
