Morally I'm totally with you, what I'm talking about is his communication and marketing talents. 
I just see a shitcoin named Tron in the top 10, and it can be argued that it was largely from Justin Sun's marketing efforts.
Same goes for Bitconnect for example, doesnt mean I endorse them morally.
I'd prefer if these skills were used to further the good in the world too, instead of pumping some shitcoin...
