1. Their shareholders would be happy. And the CEO will get attaboys from board members. Taking a tough stance on Piracy costs a CEO nothing. Anecdotes matter little, but I have seen in many cases, when gaming companies adopted new DRMs, people actually bought their shares. And not dumb people, too.
2. There are some assholes who don't want poor people having their things. Some do it for the image purpose. Think of Apple hardware. Older models can easily be sold at a much lower price. Save some very old iPhone SEs, they don't do that. If every Tom, Dick, and Harry owns something, it dilutes a product's value to many people. People want to own rare and exotic things.
They still don't like that people can pirate, whether or not in impacts their bottom line. Also because they're so vigilant about protect their IP, that's kind of an extension of the behavior
