Perhaps my comment wasn't clear. I'm against making developers perform operations and QA tasks too. It's the author putting devops and full-stack engineers in the same basket that I question.

That said, developer/unit testing is one aspect of QA you just can't offload to a separate team.

Why hate that? The work is part of what is necessary to deliver software. It's like saying you want to be a general contractor on you own house but don't want to have architected plans, framers, or a final inspection.

I don't want to be jack of all trades, I really don't have QA mindset and I don't like software testing as a black box, I prefer unit testing. All of developers on my team hate when they have to do QA stuff. It is like being hired to do plumbing, but being forced to do gardening :) It is all on the same property but completly different tasks and skillsets.
