Not op - as far as I can tell they weren’t particularly warcrimey for WW2.
They killed a bunch of German POWs during the invasion of Sicily and killed 20 civilians while burning down a town for a supposed civilian killing a commander (turned out it was an enemy combatant).
Both deeply abhorrent but not “inventing new crimes”
They’re scum for the grift but flappy bird doesn’t deserve a trademark. US IP laws are draconian enough.
