I'm not opposed to the forks, there are 31 forks in github alone. My gripe is with at least three fork, two being distributed under different names and whose only patches are a name changed. Those may not be illegal, but are unnecessary and unethical. The last fork is being distributed with just a simple change of name also but being sold and no instruction or apparent source code is being distributed.
