re encryption

I ran a small software company in the '80s. We did the unthinkable:
shipped our software with a money-back guarantee. Anyone could buy the
software, copy it and then request a full refund.

Return rate: 0.5%. Of the returns we guessed that about half of them
were for perfectly legit reasons.

Treat your customers as if they're all honest and ethical. Most of
them will be. The rest will defeat your encryption efforts or just
skip your product.
