Because no sufficiently deep-pocketed plaintiff has chosen to do so
yet. Don't incorrectly infer anything about the existence of a cause
of action from a lack of legal proceedings so far.

That may or may not be true, depending on the nature of the
interaction, and the arbiter of truth in this case is the court
system, not you or I.

There are no dearth of legal opinions on this matter which differ
quite radically from your interpretation here, quite a few from
lawyers. As far as I am concerned (and the GPL too, if my
interpretation of it is correct), any code is a derived work of my
code if either a) it directly makes use of symbols in my code or b) it
cannot execute unless my code executes, such that its distribution
without my code would be useless.

No, you are referring to a restriction on the limitations in software
licenses which is separate from copyright. Copyright law does not talk
about interoperability at all. And even the applicability of the
restriction to which you refer is jurisdiction-dependant as well as
context-dependant (see the DMCA).
