Paying for things is the way that people 'vote' in a capitalist model. When you buy songs by an artist... the artist makes MORE songs. When you buy porn from a paysite it updates more often. When you buy software they make better versions of that software.
Not paying for things in the 'free world' people think they live in is the number one reason why product quality overall sucks as compared to the past. As more people figure this out free will fade away (and so will poor quality), eventually being replaced by what we had before.... high quality products worth buying and people who pay for them.
