I expected this answer. I have actually talked to several companies in this field in Asia, and they all say the exact same thing, so it is not just Best Buy.
I think we all agree on the fact that complying with the licenses is extremely simple and I do think that enforcement to have this corrected is actually a good thing, since it often serves as a wake up call to companies to fix their processes.
Asking for fixing things that are outside of your own copyright (and which is unlikely you could enforce easily anyway) like binary kernel modules, review rights and veto rights for future firmwares and devices, plus asking to be reimbursed for that review (again, this is not just something that Best Buy said) sounds like a clever hack, but they are overreaching and shooting themselves in the foot here, because it is asking for your software to be replaced.
I would also be surprised if these claims would hold up in courts in Europe. I very much doubt it (but IANAL, I just like to hang around them and ask them lots of questions). I should ask more lawyers about this.
