I guess the solution is some sort of federated search dongle that submits the search query to google, gathers the results, and throws out everything that isn't actually verbatim or otherwise matching the search query.
Assuming it's work for hire...
If it was work for hire then the client owned the rights and original poster, samzenpus, had no right to put his own copyright into the header. The new developer/maintainer wouldn't have that right either.
If it wasn't a work for hire and samzenpus was the original author, then he has a case for copyright infringement. A cease and desist letter might get the headers restored.
