While most are against new government taxes, what about Microsoft "taxes"

Ok, now I've heard all of it. Now Big Business, such as Microsoft, costs our governments plenty of money, albeit discounted per license, but when a government wants to be more inclusive toward it's citizens, Microsoft balks? Hmmm, me thinks this is the wrong approach by Microsoft and I think that this is the break in the Microsoft money dike that will erode their dominant position.
