> It is right that the author of a creative work get protection for having conceived that work and reduced it to tangible form. This is incorrect (and I didn't grow up in the digital age, unless you call 4 function calculators the "digital age"). There is no such right. It is not a human right, nor is it something that you are intrinsically entitled to have. Copyright is something that is endowed upon you by the gove…
Your parent poster said 'it is right', not 'it is /a/ right'. You're attacking a statement that didn't exist in the parent post.
So, now I am a bit confused. Do they believe that they are morally entitled to a monopoly, or do they believe that it is simply a good idea? Because in the first case, it doesn't really alter my post. From societal standards, they are not morally entitled to the monopoly. The parent is, of course, free to disagree but they stand against centuries of legal history where this just hasn't been the case. It would be incorrect to state that only those who grew up in the digital age disagree.
If it is the second, then I will agree in general, but I think we should be very careful to balance the benefits. I believe that copyright on APIs will cause significantly more harm than good. So in this specific case, my opinion is that it is not right (as in not a good idea) to do it. It is certainly a debatable issue, though, with many reasonable arguments on both sides.
