My comment was a bit harsh as I wrote it, but, it's genuinely so depressing to read about the cool things people create, and then seeing them vanish from the internet, as morals-less lawyers swoop in and claim various falsehoods—on the calculation that the victim won't have the resources to fight against professional patent trolls. Against experts who specialize in legal extortion, such as this example.

- "...regardless of how we felt about the validity of this patent pressure, we could not devote the time, finances and energy to take up that battle"

These types of predators are the natural enemy of HN.
