"But those people would not have bought the software anyway"

Then why do my sales stop or are reduced to a trickle the moment my files start to be shared?

I frequently get enquires from folks running my scripts. I'm always happy to answer their questions but when I ask for their sales verification the email conversation sometimes mysteriously goes cold.

By all means wrap yourself in the warm fuzzy security blanket of the idea that it is not really a loss. Me? I'm standing here in the cold light of reality.
