Have to agree with the comment below, DevOps folks/teams I've worked with seem to have both a superior attitude and an inferior knowledge of good practice and good habits when compared to developers.
Gee, I don’t know. When developers are constantly flinging half-tested and wholly unoperationalized things over the wall, perhaps it’s normal to develop local-maxima defensive practices.
I am a software developer and yet when I hear a developer open their mouth to complain about nearly any other aspect of a product team, be it QA or infra or UX, it has this weird tendency to resolve to Anybody But The Developer causing an issue.
Then perhaps you ought to sit with the folks I'm consulting for at the moment, who have a DevOps team who have failed to deliver a reproducible system for over two years and still have the attitude that they're the superior race.
That said, they are highly paid, London financial world folks, so you'd hope they'd be good.
I also hear from a developer I work with who has recently defected back from devops style roles to devs that this is not atypical. He seems to place blame at least partially on "The Phoenix Project" for the attitude!
They seem to have bought into their own myths.
