It’s kinda difficult to find cracked Linux-native games, though one site that I do know which has a section for it is Torrminator. Don’t really want to get in trouble with the mods so can’t post the link, but if you do end up finding the site, then I hope it has whatever games you’re looking for.
Adopting leftist music by perverting its meaning is pretty much the M.O. of far-right anthems/songs, no matter what the song was about originally. See: Tomorrow Belongs to Me, Fortunate son (to a milder extent), Born in the U.S.A as some of more well-known English examples.
I wonder if this was an attempt at doing precisely that, or was it just some publicity stunt for the movement.
