Because it needs to be said again and again and again:
Just stop. Stop. Stop putting DRM on media and inside media players. It doesn't do what it's supposed to do. It gets cracked every single time. You are throwing money away. You are alienating customers. You will lose customers and piss off the ones you keep. It's not worth saving 1% on the backend while losing 10% on the frontend. You cannot keep up with the savant hackers who can crack whatever you throw at them in a matter of days. You are introducing countless unintended consequences. You are impacting things that actually matter: doctors who can't afford false positives from a bogus certification scheme, charities using outdated software having their systems bricked, libraries unable to archive material properly. DRM is a cancer. Stop.
