Well perhaps I'm the one that's confused then. > Why shouldn’t a company be able to copyright the implementation? This is what a software license is - software licenses are, to my knowledge, just a form of copyright. The question here is if the API is copyrightable, not just the implementation. In my opinion it is, the API is, as you say, part of the work they did. Honestly I feel like I have to be missing something. Articles like this exclaim that there is a consensus among programmers that I'm wrong, so I feel like I've got to have misunderstood.
