Pragmatic and/or/nor Theoretical
I suppose that, as with most things technical, there are theoretical considerations and pragmatic considerations.
If so, the dichotomy can blur or give rise to false understandings? For example:
Pragmatic
Suppose I make chips, electronic circuitry stuff and I have a way to put some semiconductors together that might have an appeal to people involved with electronic games (hardware, firmware, software, assembler and customer oriented). It makes their stuff run better, look better and gives their customers a more moving experience and, well, they can charge more than the competition or other not possessing that technology or one similar to it.
So rather than make the extra bit available for free on every chip I make I ensure it is lockable and only people buying the right to use that bit of silicon will get the key. No copyright = no key.
The model makes sense to me because I can charge royalties on top of a general "copyright fee". If you want to buy copyright you can but then I also need a "royalty fee" for every instance of potential (emphasis on potential) use that might be made of that copyrighted, royalty accessed technology hidden behind an electronic and legal lock.
It's how I make my money dood?
