Well, it is sort of amusing that you quote a passage that clearly
contradicts what you say.  "non-free SDK library" is not the same as
"my program".  Very obviously so, since "non-free" is only a concern
when the library is copyrighted by someone else.  If it is your own
library, obviously it is not "non-free" to you.

So indeed, the cited FAQ entry does not at all support your point.

Rubbish.  An independently created work never becomes a "deriviate"
from something else just because something else is created for the
purpose of using preexisting work.

Fortunately, neither of them claim utter nonsense like that.

That is your prerequisite, though probably not deliberately.  You just
take your mistaken interpretations of GPL and GPL FAQ, make yourself
believe them out of some twisted sense of loyalty, and then try to
spread what you made yourself believe.

Unfortunately, you are not doing your cause and your heros a favor in
that manner.  And it is not helped by your refusal to actually switch
your brain on instead of regurgitating what you somehow construed your
references to state.  "Wait, I must have got that wrong" is something
that never occurs to you.
