At the end of the day, whatever the source file looks like, you’re turning it into an analog signal in order to make the speakers move. So how is it at all effective?
You can even send a digital stream of the bits over Bluetooth to speakers. So it seems like the ability to decode it is a fundamental requirement for it to be a useful file. So why even bother? It seems like it would be trivial to copy into a different format.
All DRM is like a padlock. It only stops people who don’t really want to break it in the first place.
DRM: Giving people a lock, the key, and unlimited time to play around.
