I remember thinking exactly that, when Microsoft was hit by the $100M Stac Electronics judgement in 1993. "Surely large companies will understand now that they have a lot more to lose from software patents than they could possibly have to gain," I said to myself. "I'll bet they're calling their pet Congressmen and writing checks this very minute."
I've been wrong before, but not usually that wrong.
I'm sure there are a lot who wouldn't care, but MANY would leave (including myself), and recruitment would dry up. It would be a disaster.
Despite what hacker news comments would have you believe, Google is (in my strongly held opinion) a force for good in the tech world, and very genuine in what it tries to accomplish.
Becoming a patent troll would undermine that sentiment.
