In my thinking, the money is not wate. Just think how NED wasted the money from Steemit inc. and which near Zero development was going on.... This was true waste of money. Even the endless Power down....
Justin is using it for Marketing. If it was right to spend this for dinner, we will see only in the future. But the effect is allready, that Tron is more in the media as before. So in that case, i think its right spend. Becasue the poor people have help, and Justin gets in Contact with the right man, Tron goes more famous. If he spend 4 million on TV advertinsing, ( which is as well not much for Worldwide) than even than people will say anything against him.
If the Money for the dinner was spend without the social help for the poor people than we truly can say that this is something different.
