@alienghic @cwebber @Shamar @kaniini @starbreaker and this (as a licensing scheme) is 100% fine, because anyone has a clear choice -- either you go with GPL, or you pay.
Notice there is nothing about "noncommercial" in the GPL.
That's my point, NC is not necessary to achieve what people think it's needed for. And it's counter-productive and problematic in general.
