If the recipient can't be convinced to pay without artificially restricting their freedom in the work once legitimately received, you're doing it wrong.
Except the problem is probably more like they're being offered a discount for artificially restricting their freedom, because the entrepreneur is taking the up-front risk of development and banking on the later growth of the sales to receive the return.
Without understanding the risk/return model, you can't really understand the benefits to developer (and user, in fact) of the proprietary model, and are unlikely to overcome it :)
