Apparently it is an executive order from Biden causing the chaos.
I do find it concerning that he made no effort to defend maintainers who weren't exactly no name contributors. He had no issues stating his other political views.
I also hate Russia, but I see no benefit in going along with clipping dedicated FOSS contributors without even acknowledging the absurdity of it.
I can understand the US not wanting people to directly help the Russian government or other enemies, but I don't think FOSS should be a concern. I especially don't think alleged defenders of FOSS should just go along with this sort of treatment for contributors without calling it out as bullshit.
