I feel like the guy who's about to say "what about all of the good things Hitler did?", but does patent trolling invalidate the good things this guy has helped contribute? I feel like that the tech community, for all of our preaching about meritocracy and rational discussion, we have no problem piling on a fair amount of demonizing of people who engage in things we don't agree with, but may have some social value. One person's patent trolling is another's patent protecting. Again, none of this to defend his worst actions, but it's not like Satan created IV and uses it to eat children. Yes, this is a puff piece, but I'm always surprised that our community has no issue crapping on some people with no acknowledgement of anything positive they add.
