Yep. I think the WPScan guy doesn't understand how the GPL works... and seems to think that having a "wrapper" around it for commercial/non-commercial somehow lets him circumvent the GPL intent. Forking the code from before the license change is an excellent way to keep free software free - and yes, I think he'll have to get permission from every prior contributor before he can legally change the license.
