Protection Racket?

You wouldn't expect to buy a house and then be charged extra for having locks on the doors or windows....

A cynic might say that by charging extra to resolve the security vulnerabilities it's flagship product contains, M$ would have little reason to eradicate such problems in the first place and perhaps actually have an incentive to make sure that a few such issues are always included in their product so that they can get some extra bucks by offering protection in the future.

Here's the story on CNN

You can just imagine BillyG the local glazier walking into a grocery story carrying a brick, admiring the quality of the plate glass window out front but warning the shop keeper that 'the kids' in the neighborhood are quite troublesome. Of course, he can keep 'the kids' away and ensure the window stays intact for a small consideration to cover his time and trouble.
