I just realized something that might explain how we see "OU" differently, pronunciation wise.
When I see OU, I think Oh-You Sooners ... it's all OOOOO, as in half of OOOOO and AHHHH. An expression of joy, of wonderment, and one might even say, of delight.
But when a Texas fan sees the "OU", I'm guessing s/he mainly sees it as one big
OUCH
Which of course (and there's a third pronunciation of "OU" in course), is a whole 'nother perspective. So, I get it.
But when I see DOOOOOOOOOOOOOOOMED from a Texas fan, inside it triggers an OOOOO and an AHHHH and so lurking in Doomed for Texas is most certainly an OU.
