I wonder if this guy thinks there is ANY software that is worthy of being purchased or is it all tainted in some way? Has he ever purchased a can of soda, a movie ticket, a laptop computer, etc.? How does he even subsist in our corporate consumerist society without compromising his highly developed sense of right and wrong? I don't know but gathering from his hateful disposition it must not be easy.
As far as I understand his philosophy, it has nothing to do with paying for software and all to do with your freedom to modify said software whether you paid for it or not to suit your needs.
