It seems to me that the OP's real objection isn't to "DevOps" but with the reality of the software industry. He's upset that developers often are asked to do "lower" work. I find that a bit simplistic on his part. If anything, DevOps at its best is about elevating the ops work (by recognizing automation possibilities).
The issue is that employers are horribly inconsistent. They demand specialism in hiring, but refuse to respect specialties once they've pulled people in. Thus, you end up having to interview like a real computer scientist, only to find that most of the work is mind-numbing for a serious programmer, but that there's no one around at-level for it because "we only hire A players".
DevOps didn't do this. The problem is the industry, not one concept.
