Don't use one of the most permissive licenses in existence and certainly not one that doesn't provide copyleft. This is all very well established at this point and yet somehow the GPL seems to have gone out of vogue.
> Don't use one of the most permissive licenses in existence Does it matter what license you use if they actively ignore the terms in the license you did chose? MIT requires attribution, but they didn't. Why would any other terms be different? You surely could have put "You must license your project the same as the one you forked from" and they still would have ignored it, not sure what the difference would have been…
No, they would have found something else that wasn't a pain to steal.
