Wonder why guys like Sonnox, SSL, Kush Audio, Eventide, Avid, Exponential Audio et al use iLok2 if piracy does not matter? Presumably they have a pretty good feel for the situation. Then you get all the pinheads, not understanding elasticity of demand saying " if you charged half, you'd sell double" as if these top dsp coders are a pack of morons.
Even when developers say they don't care about the piracy component they sometimes care. Eg Hornet plugins who had a "I know you are not going to leak it on the internet, so no copy protection for you" philosophy, recently changed his mind and added a type of watermark because he saw some of his work floating around warez sites.
Where is the evidence that piracy does not dent sales?
