> But what if clicking 'decline' meant that you could actually state a rational reason, and expect some sort of human response?
Sure, no problem. Just expect to pay twice or three times the original price of the program, to pay for the administrative staff required to negotiate with recalcitrant users.
> And in the time it took to get that response, you could use the software?
Never happen. In many cases a program is a collection of modules from different vendors, all with their own requirements, and none of whom would be likely to agree to negotiate with individual users about how they can use the program. And certainly not in advance of forging an agreement -- a contract -- between themselves and the user.
In mass marketing, what you suggest is simply impractical. It's not as though a program is protected by an ironclad international copyright except for John Doe of Main Street, U.S.A. who is using the program under protest while his lengthy and articulate objection winds through a corporate bureaucracy. This isn't realistic.
It's not about fairness, it's about practicality.
