It's so frustrating that Japanese developers are either so out of the loop with treating PC gamers with a iota of respect, OR they get contracts that they don't understand that fuck over real buyers.
I'd also recommend joining GamesThatHateYou and following the curator since it'll tell you if a game stopped using Denuivo or just switched to a different but similarly terrible DRM.
They also tell you if a game has had Denuivo in the past and has removed it, in case you don't just want to avoid Denuivo but developers who use it or ever did in the past.
