API vs implementation
Authored by: JK Finn on Wednesday, May 02 2012 @ 12:01 PM EDT
So the existence of a non-GPL alternate implementation changes the picture? Does the alternate need to be functional vs simple stubs? What if dynamically linking against the alternate results in execution without runtime errors, but that doesn't actually accomplish anything?

Well, if your code does not actually need the linked library to do anything... why link against it at all?

Again, given the context of the article, the point here is that the API is not the work under copyright, the implementation is. If your code demonstrably works to spec when linked to the alternate implementation, stub or not, it is arguably not a derivative of the GPL implementation. If you require the GPL implementation to be present at runtime then that argument fails.

The main question of law is the extent to which copyright law gives the copyright owner the right to make/enforce rules. Clearly there has to be a limit, the question is where it is.

That question cuts in more ways than one - do you have the right to require someone else to make a copy of some third part's copyrighted content without that third part having any say in the matter?

P.S. The original anon, I presume? Would it be a terrible burden to put some kind of nom de guerre in the comment if expecting discussion - the threading gets confusing quickly among the anonymous.
