There’s a concept in linguistics known as descriptivism vs proscriptivism. We either accept that things change meanings and pronunciations regionally and over time, or we try to absolutely state that there’s one correct way, and every other way is wrong.

A major issue with the “I’m right you’re wrong” approach is the in-group decides who is right and wrong. Regional slang is just wrong, not an equally valid way to speak. Those with formal educations are inherently more correct, and thus their grasp of their native language is more correct. This doesn’t really make sense when you think about it, other than to put down groups perceived as lesser.

Additionally, academics can convince themselves of one thing, and totally fail to be relevant to the real world. This leads your average person to become disenfranchised with academia and talk about how academics in their ivory towers have no understanding of how the real world works.

Anyway, that’s why I pronounce it joeff.
