In my own experience I don't think developers were ever pushed to become devops (as the article asserts).

Instead, about 40% what was called 'sys admins' were pushed to become devops. The 'sys admin who knew cfengine' became a 'devops person who knew ansible'. Deploys and cloud APIs just became another thing to automate.

The bottom 60% - the shit ones who got paid 120,000GBP to copy paste commands they didn't understand from word documents into Solaris 8 boxes in 2010 because they couldn't actually automate anything - left the industry.
