I think it's part of a general push by the bleeding edge away from hosted-cloud solutions and towards controlling bits of the stack themselves. dropbox is a good candidate for replacement because storing a few personal documents to sync with your various devices sounds like something you should be doing for yourself, unlike, say, email which is manifestly harder to do right.
