If you want to fight trolls mano-a-mano in lawsuits to either invalidate patents or at least knock them down in relation to a particular product or company, then more power to you, but I personally would find it terrifying to fight such a lawsuit myself if my company DEPENDS on the victory of the lawsuit.
I'd gladly (once my company is profitable, anyway) donate to the cause to help take a troll down, however. :)
