Take a look at the original json.org license and all the problems that the "not for evil" clause they added to it had caused.

Ultimately though, if you put a non free license on your libraries, somebody will cry foul, fork it, and evil will still happen.

Basically you end up with something not legally enforceable. And will someone actually doing evil care about your license?

They would if they could get sued. But it's unlikely, so they won't.

Best cure is to use GPL, any evil company would not be able to handle *having* to give back anything to project they used /s

		GPL mandates giving forward to users, not giving back to the project. It is also commonly violated.

Well then you just use some copyleft language to ensure the same license (or something you deem compatible) is used.

Just because you can fork something doesn't always mean you're able to just change the license.
