[linux-elitists] What would be the proper course of action for a possible GPL violation?

That matters if the binary in question _is_ in fact compiled from GPL
source or derivative of a GPL-licensed codebase (but not if it isn't).
Essentially, that clause says that redistributors and distributors of
derivative works cannot provide the preferred form itself but render
that instance nearly useless by omitting intimately related files
necessary to build it.

I would imagine so, though nothing requires the publisher to ensure that
you have the ability to make the compiled binary work on any particular,
specific hardware. (This, you may recall, was the point of contention
about TiVo Series 2 and later.)
