I know the question is rhetorical, but the answer is that many people don't understand how to use git, and the preferred way of coping with this is to dogmatically declare some git feature (either branching/merging, or the various operations that fall under "rebasing") to be "Beast. Defiler. The source of all my pain." But only people who are bad at git ever post things on the internet about git! (with the exception of Junio's blog)
