> That sounds like what Software Freedom Conservancy would call a GPL violation

Sure, it is. So what? Have you got 200k for lawyers and years of your life to spend in court fighting over it?

I have personally contacted the SFC with ample evidence of deliberate and wilful GPL violations, such as providing a written offer for source code and then ignoring or flat out refusing requests for the source code. The SFC has acknowledged the vendors are violating the spirit and letter of the GPL.

Nothing happens. The SFC is one organisation with limited resources, FOSS developers don't want to spend their time in court, they'd rather develop software. Vendors know 9 times out of 10 they will get away with the GPL violation scot-free.

It's fine to put on your rose colored glasses and pretend GPL forces companies to release source code. Reality is, the vendors have a larger marketing budget than the entire SFC endowment and the vendor's legal team is happy to tar-pit requests ad infinitum.
