Patrick McHardy, a rogue Linux copyright troll who has made millions from GPL enforcement for (in the grand scheme of things) negligible contributions, has waved a white flag in a major enforcement lawsuit he was pursuing.
This doesn't change the fact he's already made millions of Euro from his legal fights and he's likely to continue.

But he isn't doing this for the greater good
He's doing it to enrich himself
Companies often comply when asked when legal action looms; his tactics are clearly designed to make him lots of money by abusing mechanisms in German law
