The entire article can be summed up the same way you can sum up bad security products: DevOps isn't something you buy or make a department out of, it's something you do, or better yet, it is a method.

DevOps is fine, bad DevOps is pointless. Just like microservices are fine, but bad microservices are pointless. Same way bad metrics towards business owners causes you to seem to add no value (which goes both ways).

That said, you can still find plenty of job postings for 'DevOps Engineer', which is part of the problem. But I suppose culture changes are hard...
