I must not have been clear. I DO blame the player, and think that the lawyers at (e.g.) LodSys don't have the slightest clue about ethics or morality among them (I also think things about them that are not printable in an HN comment). I just think the proper strategy is to defeat ALL of the players at once by changing the rules, both from a cost AND a risk perspective.
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. :)
