That's kind of like saying you'd never work for MSFT or Apple because both create DRM. If you're that kind of absolutist, yes, you don't want to work there. But Rovi is a big company and the Blu-ray content protection system is quite interesting.

The ultimate equilibrium they will achieve if they do their job properly is that discs will not be rippable when they first come out, but after a couple months will get cracked. In that time period, the studio makes 90% of their lost revenue and you still have the ability to make backups after a delay. BD+ has had its ups and downs, but I think it has the potential to achieve this. It's more than you can say for most DRM systems.
