> We have found that neither company complies properly with the GPL. Specifically, in our analysis of the facts, we have found that both Cambium and Ubiquiti fail to provide any source code for their respective routers and access points, even when we repeatedly asked over the course of several weeks, starting more than 30 days ago.

Unless sfconservancy first purchased a router, I don't believe that the GPL forces them to hand over the source code.

The mentioned GPL in the article is v2, so lifting from there, the valid parts are probably:

> a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

> b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

No part of the GPL, as far as I'm aware, requires distribution to anyone who isn't a customer.
