Oh yeah, my point of view is entirely based on my experience with small to medium sized companies, and there especially developers can be the instigators in sudden complexity multipliers.

I tried my best not to rag on devops as I am always incredibly impressed by these systems and what can be achieved and automated. It absolutely has it's place.

It's just that all the technology that big companies use become trendy and then end up used at small companies too. Small companies don't realise that the tools aren't solving the problems they have, and they don't understand the vendor lock ins and dependencies that they've introduced into their platform for no real gain.

This happens in all kinds of ways, not just devops. Your example of developers using the microservice pattern is exactly that. When I see a developer recommend microservices my mind flashes forward to all of the extra complexity that entails and how we've just turned a small monolith on one server into 6 pieces of software across distributed servers. Great for big companies, too much complexity for small companies.
