somebody has forked this repo and relicensed under MIT

[atesin]

according FSF this can't be done, to take some GPL project, modify or not, and relicense the derivative work under a more permisive license... for me this also sounds like "stealing"

this guy has taken your project, forked it, cast a number to int somewhere, commit, then relicense to mit
