Software Freedom Conservancy have been doing GPL compliance actions for a long time, especially if you consider their staff's previous lawsuit that resulted in OpenWRT existing. Also the more recent Vizio lawsuit is kinda interesting, it aims to enable any recipient of GPLed binaries to sue for GPL compliance.
