If in fact that there were massive fraud occurring by home license holders, at the end of the day untangle would know. Besides the fact that honestly how enforceable is the non-commercial part of their license is it for someone who does day trading at home (I do not) or sells a used item on eBay - according to their at home licenses - both those things would invalidate any home license that they have offered. I think that’s a bit unreasonable to be honest. If people are using the product in good faith at their home - that should be enough and geographically- untangle reports it’s location so that is easily established.
I’d like to see honest statistics of home licenses holders who abused the license in real world cases like using the product in a business environment.
