Also, I just recently heard about the false DMCA claim for the Steam version. I noticed when Steam proposed me to live an evaluation for the game but was returning an error when I tried to submit it. And since I bought it on Steam before the DMCA claim, I didn't noticed its disappearance from the store (as it didn't disappear from my game library).
My condolences. Those types of salty assholes that fill fake DMCAs are the worst...
