It's also in contrast with some of their own previous behavior. When they saw opportunities to make things faster/better, they were comfortable breaking standards (or, well, making new tech that might stand as a standard one day and asking people to let go of older standards). One example: SPDY. Another: go. Additionally, there's a whole bunch of examples from chrome where they broke conventions for user experience and drew people's ire, but in all cases they defended these decisions with well thought out (if controversial) arguments.

Where's the argument against CalDAV? (I'm not saying it doesn't exist, I'm just surprised to not have seen anything from them)
