Two things from my memory. 1. They hit some bad PR when they pushed a badly broken release in a point update. Turned out that their testing was not robust, while Lodash's is excellent, which further hurt them (this is when I first remember hearing about Lodash) 2. Lodash adapted better to the module landscape, especially by splitting all of their functions into separate packages.
