I think people use upvotes both to signal agreement and to highlight thoughtful, effortful, or detailed comments. I think it’s fairly clear that Kbog’s comments was upvoted because people agreed with it, not because people thought it was a particularly insightful comment. That doesn’t preclude people upvoting posts for being high quality.
If your point is more that people don’t generally upvote quality posts that they disagree with, then I would probably agree with that.
