The problem of vendors wilfully violating the GPL isn't one that can be solved by writing code. People who own the copyright to bodies of Busybox have chosen to enforce that copyright as part of a larger overall strategy to force vendors to release the source code to other GPLed works that they're infringing. They have the right to do that. You're choosing to work on a replacement for Busybox in order to make it easier for people to avoid enforcement actions. You also have the right to do that. I think your approach results in us seeing a larger number of wilful GPL violations than would otherwise be the case, but it's absolutely your choice.
