People like to go apeshit about DRM controls. This particular article helpfully suggests:
By far the best way to avoid DRM, is to refuse to use software that is infected with it. Better yet, you should choose software that tries to do the opposite of DRM -- software that gives you complete control. This kind of software is called "free software," and it is based upon the idea that software carries certain freedoms to you ...
And then goes on to list the benefits of freedoms of free software. The usual standard blah blah blah, you can copy it, you can modify it and add your own bugs, you can shit all over it and eat it for dinner, you can disable random seeding and distribute it to millions of users, etc. Sweet. Too bad they forgot the most import to freedom: the freedom to consume content that you actually give a shit about.
Freddy Freetard deciding to use Linux instead of Windows isn't going to stop Microsoft from writing DRM code. Freddy will just no longer be able to watch what he wants to. And NBC or whoever probably won't care because Freddy was bittorrenting all his shit to begin with.
It's not Microsoft that's causing DRM to happen. It's the content owners. Microsoft is just enabling their platform to deliver shitty DRM content. They're enabling new business models. If you don't like it, don't buy the content. It worked for audio. Anyone who matters now sells mp3's. Why would it not work for video?
But you know, go right ahead. Switch to Linux. Close yourself off from the world. At least you won't have to deal with DRM. You can spend all the time you spend hacking on your sound card driver, so that you can listen to that hot new FLAC file of live drum circle recordings.
