How to blow your foot off
The computer games industry is currently annoying their customers just as much with copyright protection technology.
When will monoliths like MS etc. realise that people with pirated copies are having a better user experience with their products than those with legal copies.
There is no "Genuine advantage" to using genuine MS software any more.
Linux (and other O/Ses) are currently failing to gain significant market share because users see learning the new UI as a barrier to entry. What MS is currently doing is making their user experience unpleasant enough, that users will eventually be pushed out of their inertia into trying other OS's.
Well done, MS, your users are beginning to weigh other options, that they would never have thought of if you didn't keep treating them like guinea pigs in your copyright protection experiments.
I'll bet Linus and co. are smiling.
