Gin? Genetics? Giant?
Do you pronounce Origin like Oregon?
I personally find arguing pronunciation as entirely pointless when there are many words in English that get pronounced different based on a multitude of factors.
People also like to argue it's an acronym, but do you pronounce NASA the same as you pronounce the first letter of each word of National Aeronautics and Space Administration?
Honestly? Just say it how it makes sense to you.
