Microsoft vs. Google

There's been a lot of to-do over the lawsuit filed by Microsoft against Google. Apparently Google hired away one of MS's top engineers and MS is suing. I don't know squat about the lawsuit or the law in this matter, but I've got to wonder what MS is thinking? So they win and this Lee fellow has to go back to working for MS? How happy will he be about that? Seems to me that he could do a lot of damage at MS if they forced him to work for them. Or will they just force him into some sort of permanent unemployability state? That's a great way to treat your employees who are given the chance to get ahead. MS has made their point, but if they win, I think they'll lose.
