I must ask why he feels so negatively affected

I can't speak for him; I have no clue. I do know he has a bad reputation. Reputation matters.

Downvotes aren't the end of the world. Some people do overreact. I think he was doing fine until he made a proposal which was firmly rejected, so he did a complete 180 and went from loving it to hating it with the flip of a switch, possibly proving his intentions were not pure and authentic to begin with, but I don't know.

At the end of the day, people are free to come and go and make any decisions they want. So he did. As did I.

High stake members have the most to lose, correct? And here this guy is attempting to take from everyone by attempting to lure people into dumping. Yet he feels downvoting him is unfair? The things that make you go HMMMM...
