The likely reason that you are not getting any response is that you're struggling to navigate through a large organisation. That's the most likely reason - it's inertia rather and evilness. Somebody in the CSR (or Qualcomm) legal department will know that they don't want to violate the GPL. The sales organisation and support don't know anything about the GPL, probably can't even figure out who internally knows how to deal with your issue, and it's not really their problem (from their perspective). If you want to get this resolved you'll need to find a way through their internal process. What I would do is one or both of these: a. Call their main head office by phone On the contact page there is a UK phone number, phone it and ask for legal or the PR organisation. You will most likely find it hard to get to the legal department, but be polite and persist. If you get through to PR point out that it's a PR problem (to make them care about it) and explain that you want to talk to someone in the legal department. Make sure you get the name of whomever you talk to and their number - that way you can be persistent but polite to someone. http://www.csr.com/contact http://www.csr.com/contact b. Contact Qualcomm legal In the privacy page there is a link where you can fax or phone notice of a violation. Yeah lawyers are old-fashioned. Send them a nice note specifying that you believe they are violating the GPL and that you would like the source etc etc. Note, the downside of this is that you will be talking to Qualcomm head-office in the USA and it will most likely take them a bit to figure out what you're talking about and find someone in their subsidiary (CSR) to deal with you. https://www.qualcomm.com/site/terms-of-use https://www.qualcomm.com/site/terms-of-use IF you land-up talking to the legal department don't assume that they know anything about the GPL. There are a lot of lawyers in a corporate, and only a handful will know anything - you want to try and get to one of those ones. You might have tried all this already - in which case apologies. Anyway, Best of luck!
