APIs are in fact copyrightable.
If that is "in fact" so, then you should be able to easily cite unassailable proof for it?
A specific implementation of an api -- Ie. the source code -- can be copyrighted. And copyrights on parts of that source code -- as determined by the BFC test -- can be be legally enforced.
But no one has yet succeeded -- though few have tried -- in enforcing copyright on the specification of an API when re-produced under clean-room conditions.

In the absence of evidence, opinion is indistinguishable from prejudice.
