Why do they do it ?
I never understand quite why Microsoft are always moaning about other companies. They have bank balances that make people's eyes water, they have money that could not be spent, yet they continue to whine and winge about everyone else 'picking' on them.
Perhaps if they kept their corporate mouth's shut, left others to enjoy peace and harmony and tried to count the money they have the world would be a better place, and the FTC would not be looking at them.
The could, of course, spend some of their money getting their software to work, and try worrying about their own back yard before looking into other people's.
