Hmm... This wouldn't have anything to do with Microsoft suffering millions of dollars in losses from their competing Bing search engine, would it? I can see it now:
Microsoft Exec: "Team, I want you to program MSE to get Google Chrome off people's computers... and make it look like an accident."
Programmer: "But sir, isn't that an extremely unethical business practice?"
Microsoft Exec: "Who cares? Just reprogram MSE to kill Chrome. If it works, we'll make Bing a huge success overnight. If people get mad, we'll just patch MSE back to the way it was and no one will ever know."
Programmer: "Sir, this plan is both highly unethical and unbelievably stupid. It's not right, and I won't do it."
Microsoft Exec: "I understand completely, Johnson. That's why I'm planning to give out special awards to all Microsoft employees who value their personal integrity over making lots of money. The awards are printed on beautiful pink paper."
Programmer: "I'll get right on it."
Okay, okay; I'm done beating up on Microsoft... for now.
