People often forget the Microsoft right before Balmer was slapped with one of the largest anti trust lawsuits in decades. People wonder why MSFT hasn't been competing aggressively for the following decade... It's because they've been afraid of anti trust litigation yet again.

I've had a couple of conversations with people in semi-upper levels of MSFT management. Long term Microsoft employees are still scarred from that litigation. So much that it still comes up in conversation 12 years after the fact.
