Well Rowe could've helped himself a bit by not trying to be cute and asking for $10,000. If I were 17 and noticed that Microsoft had taken a negative interest in me, I think I might have consulted someone before making any move against the giant, and it surely doesn't seem like he talked to his parents or a lawyer or anything. It says "'I never even thought of getting anything out of them,' he said, adding that he only asked for the $10,000 because he was 'sort of mad at them for only offering 10 bucks.'" I seriously doubt that anyone would advise him to take that position. It sounds to me like he was just doing it to be a butt, which isn't a smart thing to do.
You can see that no one was actually getting sued until the kid decided to poke the tiger with a stick. While I don't condone Microsoft's actions, and do think it was ugly to offer $10, Rowe should've just quit while he was ahead or gotten some actual legal advice. And if he did....well....hopefully he won't be taking that lawyer to court.
