The pessimistic guidance dovetails well with Zuckerberg's recent, wide-ranging interview with Kara Swisher[1]. FB has been the darling of tech and general media, until the last 2 years--turning a great brand to an increasingly toxic one. By Zuckerberg's own estimation, FB's "retooling" needs 3 years, and they are about 1 1/2 years in, so the guidance reflects that timeline. If they deliver on that timeline, a rough 2nd half of 2018 and all of 2019 is to be expected.
