Yeah, that's my understanding as well, from "ripped me off", implying stealing or something negative. Having the (almost) same API surface as another MIT library is hardly a "ripoff" but a re-implementation. Edit: since new evidence has come forward (https://news.ycombinator.com/item?id=27275379 https://news.ycombinator.com/item?id=27275379) I think we can all agree that Lodash is a fork of Underscore.js, nothing more and nothing else.
