The DRM problems are well known (a partial list):

1 - it does not deter pirates (they are much smarter than the average corporate developer);
2 - it inconviniencies (read pisses off) the legitimate users;
3 - your computer must be connected to the internet (especially for randomly phoning home apps that, after a few connection misses, decide that your copy is illegal);
4 - when the parent company goes belly up, you lose your stuff (happened with a few times DRM music);
5 - opens all kind of security risks (a hacker can hijack the DRM procedure);
6 - bugs that make the DRM server decide that your items are illegal;
7 - connection problems twarting access to company servers (either local or more generalized, like DNS problems);
8 - adds complexity and development cost to the program;
9 - increases need for support to users.

Bye.

P.S.: I remember a certain person mockingly citing a Churchill's speach ("we will fight on the beaches...") when, many moons ago, I pointed out how things would pan out. Things are heading the way I predicted.

P.P.S.: we are out of the "libelous speculations" area, aren't we?
