It wasn't really a comment on the tech of DRM but of the business threats that require its use.

That being said, streaming content security is more than just DRM and DRM is more than just copy protection. There's a whole suite of tools inside DRM systems to manage content access at different levels and rulesets that can be applied for different situations. It's still fundamentally controlling an encrypted bitstream however. But I've implemented a great deal more than just DRM in order to build a better content security platform. Transit level controls, advanced token schemes, visible/invisible watermarking, threat/intrusion detection and abuse detection, there's quite a bit that can be implemented.
