Patrick McHardy and copyright profiteering (Opensource.com)

I've personally dealt with folks who take a "bugger off" attitude, most notably Senao/Engenius.

Their products are built on OpenWRT, but they *refuse* to release their kernel sources for at least some of their products. They do however occasionally release "GPL sources" tarballs of everything but the kernel -- Albeit after some cajoling.

They are an example of a company that has absolutely no excuse for continuing to violate the GPL, and IMO utterly deserve the stick to be waved at them.

It's funny. The Senao products I have contain the proprietary Atheros wifi driver. Back when I was still in that line of work, Atheros required some truly onerous licensing requirements to ensure their driver (and the developers working on it) in no way co-mingled with other source code, and had per-unit royalties which required proper production accounting, and massive penalties if any term of the (long) agreement was violated.

Yet somehow the requirement to release their complete corresponding source code to the kernel is too much of a burden for a publicly-traded company who posted a US$3.4M profit (on revenues of about $57M) during Q1 2017?
