My point was chess engine (application) not OS. OS is a special kind of software.Don wrote: It's not yours. Try putting this OS on another computer. Certainly, this should be a reasonable test of ownership - shouldn't I be able to buy a second computer and still use the software I already purchased on it?
I think you have to admit that you are not buying the software, you are "renting" it.
Nevertheless when i bought a bike i will be not able to swimm by it

It will be not the test of the ownership.

By occasion thanks for the free Komodo SP. From my point it is free program because many users are dedicating 1 core for analysing 1 game when playing many games paralelly.
