You're right on both statements. Some think that one of the reasons that Microsoft got sued was because it didn't have any lobbyists (or only a couple, if any) and the other tech firms had quite a few.
But hey, that's only what the US Courts, Circuit and Appelate, thought after reviewing all of the evidence, even the evidence that Microsoft's lawyers got caught forging.
I wonder what the response would have been if it had been some company like, say, CBS that got caught faking evidence....
Oh, wait....
