The problem with Jews (or rather the problem faced by Jews) is that you don't have to count just Jews who are into all kinds of subversion activity, but also a large number of their non-Jew affiliates who always happen to be some pretty nasty characters. So you have a mass that provokes negative feelings, and manages to outweigh any positive contribution made by Jews.

And since you mentioned the specific situation, (Jew) Aaron Swartz is largely forgotten by the public while some like the ones you mentioned made a fortune by playing the game and jumping on the "fight whiteness and censor antisemitism" wagon that ADL started. So, instead of having people like Aaron Swartz as an example of Jews in the public sphere, you have the ADL/AJC crowd along with their large group of orbiters and ohanians that represent what is wrong in this world.
