yes plus variations ;-)

Yes, but that's not what I said. I said there was no obligation to send
changes back to original developers, but that it was polite to do so.
Obviously, if the original developers ask for the changes then yes, but if
they've failed to do so there is no obligation.
(The feedback appears to indicate that they have asked however)

In fact I can take GPL code, modify it and use it internally without either
the original developers or any third party knowing I've done so. I'm under
zero obligation to inform anyone of my actions or changes. If however I
start distributing the changed code it must be done so under the same
licence, and upon request I must make the source available.

There is no obligation for me to indicate what I changed from an original
code base (code or docs) only an obligation for me to provide the source
*on request*.

Manners imply shipping the compiled product with source, but it's not
necessary or necessarily a rule followed by everyone.

Ok, then any person is welcome to contact those organisations and request
the source. If they fail to provide it you can take the matter up with the
relevant people at the FSF.


(well technically only copyright holders can do so)
