Mmmm... There is a certain segment of the tech industry that is morally opposed to piracy, and actively pursue those people. I know because I've seen the negative connotations they've received. Had a candidate with a homelab, peer inferred it was for piracy, didn't want to hire him because of that.
I've also seen it in the weebs and also brainwashing Japanese Corp culture.
