I have a few personal rules about it, eg. I'll try not to pirate smaller, independent things where it might conceivably screw over the creator, but other than that it's all fair game IMO.
As a side note, it's been interesting to grow up hearing non-stop from the corporate world that piracy is evil and is killing art or whatever, only to watch them do a full 180 in the last couple of years now that they need to pirate the entire internet to train AI.
