> To request sources under GPL you need to get binaries first.

This is a common misconception, at least as far as GPLv2 goes. If you're distributing commercially then you have two choices:

1) Include the source when you distribute the binaries (GPLv2 3(a)) 2) Offer the source code on demand to any third party (GPLv2 3(b))

Of course, Elbrus may be distributing under the first of these, but if it's the second then there's no need to obtain binaries in order to make a request for source.
