I am with you.

DevOps is a methodology. DevOps as a role or team name is a fantasy from people who do not understand the methodology.

If you want DevOps to work, your Ops must be member of the development team, take part in the sprints, etc. But many company do not want to do that because they want to separate ops and dev budget/accounting and do not want to hire enough people with ops skills.

This is not true, you can make it work well either way. It's about people and processes, not about some specific setup or way of grouping people
