Try to see it like the Dark Tower- infinite levels of similar realities spinning around an axis (the Tower). In one, there's the Superflu, one has NozzALa cola and the others haven't. Okay the filmmakers aren't exactly Stephen King, but if it works for him, it can work for Trek.
It's just not a big deal, I think. I wouldn't let some awkward comments ruin a film for me.
My only care is if I come out of the film entertained, Trek being a work of fiction is by its very nature an alternate timeline apart from our very own.
What matters if alot of people have fun watching it nothing more or less.
