Interestingly, the Linux foundation had to remove several Russian maintainers recently because of the sanctions.

I have not looked into the details on the matter, but from what I gleaned it seems like they did not want to (don’t punish the individual for the sins of their government), but were made to. Linus Torvalds apparently made a statement on the matter that I still need to go read.

I could be very very wrong on this and am open to being educated.
