I don't think Chomsky's relationship with Epstein is in any way defensible, but I've seen similar comments to yours all over the interwebs and I'm confused by them. Chomsky never decried capitalists or told us to be suspicious of them on a personal level. Or at least, not in any of his political work that I've ever read. He was anti-capitalist, but he didn't have a simplistic view of the world where individual capitalists were inherently evil.
