Talking to McHardy & misplaced blame for his actions

Whether “they haven't a leg to stand on” would be up in the air. Remember that Christoph Hellwig got his case against VMware dismissed because the court thought his individual contributions to the Linux kernel weren't sufficient to give him standing to sue. If that happened to McHardy he would have a real problem right there, so this may be a strong disincentive for him to actually sue somebody (and, in effect, roll the dice about the ongoing viability of his “business model”).

The other problem is that German civil law only deals in actual damages, not punitive damages, so McHardy would have to prove in court to what extent he was personally defrauded by company XYZ's GPL violations, which again might be difficult to do in actual practice.

Finally, the future-contractual-penalty-for-copyright-and-trademark-violations racket here in Germany is the hallmark of sleazy lawyers. People who have been around the home computer scene in the 1980s and 1990s may remember the late Günter Freiherr von Gravenreuth, who basically turned this into a cottage industry, but the practice has been alive and kicking in various guises ever since.
