When Flickr did their DevOps talk in 2009, most of the infrastructure engineers I worked with at the time saw the trend in reverse. The people wearing the Developer hat were relying on our team's ability to automate anything, so the Ops team ended up being the team that best understood how the whole system worked.
In 2009, DevOps seemed like there was finally a reasonable answer to Taylorism. Engineers and Programmers and Hardware Technicians and Support Representatives were not cogs in a machine, but humans that could collaborate outside of rigid boundaries. Even at the lowest levels of the support organization, individual workers along the chain could now design their own tiny factories.
From there, it's just a matter of communicating tolerances properly up and down the chain. I am probably over-romanticising these notions, but it certainly felt exciting at the time. Not at all like the "fire your IT department" worldview it turned into.
