FreeBSD – a lesson in poor defaults
This person means well, but suffers from the same myopia a lot of security-first people do: making these changes to default settings is a huge violation of expectations, and the changes need to be widely publicized once they are decided upon.  Suddenly dropping support mid-cycle for tons of things will result in pitchforks and torches from people who, despite the constant insinuations of this document, do in fact know what they are doing.<p>This document, in short, makes a great to-do list but completely ignores the roadbuilding that needs to happen to get people ready and on board.
