Microsoft and Mandatory Digital Rights Management
Mandatory DRM is not to Microsoft's advantage. If there's a law mandating DRM, it will be based on a publicly-available standard that changes in government time. That means anybody will be able to write software dealing with it. If there is no mandatory DRM, but some media companies use the commonest proprietary standard, Microsoft stands to gain. It can change the standard every year or two as competitors start to accumulate.
In other words, we'll have to be allied with Satan.
