maybe I'm being stupid, but i'm not seeing the issue here. having your code public means that anyone can copy it and use it. forget about respecting licensing and what not. if you don't want anyone copying your code, you have to keep it closed and not publish it to a public repo. i don't think this is necessary a github issue. I can copy code from any other service (gitlab, bitbucket, self hosted repo) as long as the repo is public.
