Eh... his heart was in the right place revealing all those dirty secrets and it's impressive that he kept wikileaks running despite all the bullshit he had to put up with, the problem was just that he's a massive fucking sperg with delusions or grandeur that fucked up more than he succeeded and in the grand scheme of things (as far as I know at least) never really achieved much.
I am always impressed that media managed to change public opinion about him so drastically.
It also was semi successful to make Julian Assange less relevant via Edward Snowden.
There is really nothing that should make any reasonable person dislike the guy.
