They should be angry at sony? wtf?

It's literally their job to keep their consoles safe, this is not just about piracy. A vulnerable console could do all kinds of stuff users don't want.

Then also piracy: The game industry is already struggling, good luck explaining that one of the rare non live service offline single player games (after all those are the games most hurt by piracy), which has been in development for years, didn't sell because you left a disclosed exploit wide open and now everyone loses their jobs.
