If you are going to open an angle of attack, its generally good to know that you can win that battle.

To win though, would require them to commit more and more cash (as competitors start pouring in money as well). This would pollute the hiring pool, inflate long term expectations of engineers, and piss off shareholders who would suddenly see Apple engaged in a war they didn't expect.

Besides, they could just as well use that money to pay lawyers and sue over patents, hurting competition at their bottom lines.

Its an amusing thought to play with none the less.
