I could have sworn that MS had to be dragged into strengthening their anti-copying measures from XP onwards by the BSA.

Never mind that MS tries to argue that their products have a lower total cost of "ownership" for businesses, as potential employees are familiar with MS products by having used them already. Thus they require less training if hired.

I think there is even a statement from Bill Gates somewhere about how he would rather see people use unlicensed MS products than FOSS alternatives.
