What is the meaning of "objectively better" in this sentence

Solution 1:

I'm not sure it is a pun - I think Minty's comment covers what's happening : when asked "why" people have resorted to a response that's effectively "just because", which is likely to be infuriating and suggests that they're not really able to come up with an answer. The italics are to emphasis a change in tone, which I agree would probably be sarcastic.

The rule is not to end a sentence with a preposition, but if doing that improves clarity, provides brevity or takes consideration of the audience, the question "why shouldn't I do that?" doesn't have a satisfactory answer. This leaves people who want to argue that the rule is sacrosanct with an answer no better than "because we said so".

There might also be a pun there, but if there is I'm not sure what it's on about.
