I don't think that's true.

When the parent comment made that observation, they attached the caveat they might not be as skilled as others. They were already fully aware their potential lack of skill might affect their opinion of the product. All you did was repeat that same claim back to them, as if they weren't already aware of it which is a pretty uncharitable interpretation. A steelman interpretation that you could've said would assume there are some low-hanging fruit new or inexperienced developers would benefit from greatly (not just typing as you suggest), but once you develop a certain level of skill, Copilot would become less useful for experts such as yourself.

If anything, you didn't respond to the strongest plausible interpretation of what was said, since you willfully disregarded their own insight into the problem.

Then to try and morally lecture someone on their behavior by applying a rule you don't even hold yourself standard to is pretty astonishing.
