There is no DevOps role and never was. It was just management twisting it into marketing scam to get devs operate systems and to feel like it is their responsiblility.
Problem is that no company wants to have Sysadmin tied to one dev team because sysadmin won't have much to do most of the time - but that was idea of devops that you should have devs, admins, qa, business analysts working together reviewing tasks from the start and giving input on what is their specialization.
Well yeah no true Scotsman - but dev ops idea is not bullshit - way people do things is bullshit.
