However, I might note that this approach is easy because it seldom accomplishes disruptive change. If you want to really disrupt a market or community, you will often face difficulty, incredulity, ridicule, and unfair play. So it may actually be in your long term best-interests not to play this way.
As a capitalist-friendly example, I'd like to point to the iPhone. Apple took a huge risk (especially financially); faced extreme difficulty in developing and sourcing the device; faced ridicule on all sides at the merest rumor of the iPhone; and had to fight very hard to not have a carrier completely destroy the product with their (still present) status quo of "differentiating" every product. However, the end result completely disrupted the phone industry. It's also fascinating to note that the "lawyer-driven behavior" has appeared from Apple as other parties have started working furiously to catch up, and finally begun to succeed.
I have worked hard throughout my career to make sure that my name has not ended up on a single software patent. When I was at Microsoft, several were proposed around work I did for Powerset (and 1 was proposed from work I did at Lockheed Martin). I did everything I could to shoot them down and stop them, because I believe they are wrong. Maybe I've hurt my career with this approach, maybe all I've done is piss into the wind, I don't know.
