This thread is more circlejerk and shitpost than anything, but let me put this here for shits and giggles:
Recently I came up with a very funky theory regarding Odyssey's ending, or rather, people's reception towards it. I couldn't wrap my head around why so many people missed the context of the skit and thought Peach rejected Mario's proposal as oppose to his (and Bowser's) behavior. I realized part of it is shitpost or surface-level thinking, but that wasn't convincing enough... Then I had a realization after talking to a fellow shipper after she made a comment regarding "dudebros."

The reason people don't understand the moon scene is because they are not looking at it through the lenses of women logic.

Think about this: Two men fervently fight each other for a woman's affection, looking more invested in their fighting than the woman herself. Men are prideful creatures (on average) so it isn't uncommon for competitiveness to sideline any other motive two men may clash about, like a woman's affection. Under these circumstances, no woman in their right mind would make a choice because at that point the woman is a mere object, rather than the objective. By logic, Peach made the right choice calling Mario and Bowser out and leaving.
...Now swap the genders: Two women fervently fighting for a man's affection. Most women, being emotional creatures, don't sideline affection as easily than a man, they are prideful still, but women would still hold the man as the prime objective regardless of pride. Under these circumstances, the most logical thing for a man to do is make the choice, because he is not being sidelined, he is still the the women's objective.

This is ultimately why people miss the context of the scene, because they only see it in the context of themselves being presented with Peach's choice with genders swapped, unaware that human logic also changes once you swap the genders... apart from surface level thinking and shitpost, of course.
