My worst example was the word GIF pronounced like the peanut butter instead of properly as in Graphical. It’s worse because Amanda Montell was writing a linguistics book about the history of language and words.
Recent example was “eschew” which is pronounced Eh-shoo but the narrator said “Eskew” and it confused me so much I had to Google it to make sure I hadn’t been saying it wrong my whole life. What exmaples have you found?
It is pronounced like the peanut butter, according to the person who invented the GIF. If “the guy who invented it says it’s pronounced this way” doesn’t make that the correct pronunciation, I don’t know what does
There is no rule that letters in an acronym are pronounced the same as they are in the words they come from. That has never, ever been a thing
