In the end I think the music industry is losing money not because of pirates but because their market has evolved. Now people can buy the one good song on an album and leave the rest behind (which cuts 90% of the record company’s revenue). That alone explains their losses. But they’re clearly in denial about it and looking for a bad guy. Music piracy fits the bill.
So imho most of the anti-piracy rhetoric is just label execs hoping there’s a solution to their revenue problem (e.g. "if we just stop the pirates our revenue will go back up")
