The founder of GIF said JIF, who are you to debate him?
people also pronounce "GAN" (Generative Adversarial Network) with a hard G even though Generative is a soft G (J).
and how do you pronounce "MUA" (Mail User Agent)? I'd go with moo-ah, even though it's not a Mail Oozer Ahgent :)
(Just kidding. But I’ll say it with a hard G until the day I die. Because...G)
So is at least one third of the English language…
