The point isn't that it is Anton's responsibility to insure that his work doesn't get stolen, but rather that if it keeps happening then maybe he might try to find some other way to distrubute his product that might make it a bit harder to steal. Using your example...if my car was broken into on the street in front of my house...I might start parking it in my garage. It isn't a fool proof system but it does make things a bit more difficult. Maybe find some way to embed his name or logo in the design of the mesh. I don't know, just an idea. And as far as having work stolen, I have had "stuff" stolen...I'm a writer by trade so believe me, I know what it is to work one's butt off just to have somebody else gain from it financially.
