First of all, "objective rules"? The problem is that the rules only state when a match may be added.
They do not state that all later discussion becomes irrelevant. You're saying that.
You lack comprehension on what these rules even try to prevent in the first place. You're calling someone pedant for having a bit of common sense and understanding what the rules entail, instead of being a robot that follows them to their most literal sense. This actively punishes supporters for not seeing the match before 14 votes for tatsumaki were cast. In fact,
I can use other Vs Matches and Staff statements to prove that the rules favor the new argument and votes to be valid.
This principle is
literally stated in the page:
"the winner is determined by the side having better constructive arguments, rather than one word/one sentence votes, and inconclusive calls hinge on whether there was a notable debate over an aspect not directly listed on profile."
It quite literally doesn't make an ounce of sense to impede the new argument to sway voters, and invalidate their input because of an arbitrary grace period.
Qawsed's point introduced a genuinely new line of reasoning that the earlier voters never had in front of them when they cast their votes. Treating those earlier votes as equivalent in weight to votes cast after the full argument is just freezing the debate at an artificially early and incomplete stage and calling that the final word. If the wiki's verdict system is built around constructive arguments deciding outcomes rather than raw vote totals, then a vote total built substantially on pre-Qawsed votes doesn't actually reflect a verdict on the constructive arguments. If a single argument is responsible for changing the perceived quality of one side's case, then ignoring that argument results in a verdict that no longer reflects the side with the better constructive arguments
EXAMPLES:
There's also the Boruto vs Kaido example where his match was literally contested and got hate because the new information that proved Kaido would lose came up, invalidating votes, and they ignored it. It's not a me thing, it's been a thing for a WHILE
