Yes you did. That's precisely what you require with non-redistribution rules.

What you say is precisely :

« Pay the bloody $10 for this stuff, and don't give it to anyone else. »

Sorry but this is not exactly the same.

I think I am allowed to use something without paying for it, just because using it doesn't harm anyone. You don't even have to know it, I have just copied a damned bunch of 0 and 1s on my disk.

We all use many things that have been designed and created by other people in the past. These people doesn't try to waste public force energy to have us charged for that. Because they know very well their creation is sooo easy to be shared. When N people use it, it doesn't cost more to anyone if N+1 people use it.

Your work as a software developer doesn't worth nothing compared for instance to a major scientific discovery. And yet you have the arrogance of saying that your work should be paid beyond the only forces of market, when scientists have never claimed anything like that.

If for instance someone demonstrate Riemann's conjecture, he will receive $1M from the finnish state, and that may be deserved. But then hopefully I won't have to pay if I want to read or use this demonstration.

Just sell your software $1M if it worths it.

Trying to sell something that can be easily copied is tricky. Asking for public force to help you to do that, is a shame.
