Uh, the current DRM technology will not stop piracy at all. It will only hinder/stop legal users from making copies of thier legally purchased software/content. In some cases, it will even alter/downgrade the content resolution (audio or video) when played back.
The piracy problem is a problem. But DRM is just another bandaid on a cut that is 1 mile deep, 5 miles long, and getting bigger all the time. Until they attack the source of piracy, they will never accomplish anything.
Of course, one could argue they do not want to stop piracy. It gives them all the ammunition to build thier power up. And it might really boil down to something that petty.
