I understand your point in the creator but I find fault in that argument.
Historically it doesn’t matter what the creator of anything prefers unless it’s an “unveiling” and they name it on the spot. People in general will take something and run with it regardless of the creators intent. The perfect example is “light saber” versus “laser sword.” (Edit forgot to add the word sword after laser)
To be honest I don’t care all that much. If you say jif or gift without the t, either way I know what you are talking about.
The problem isn’t people preferring to pronounce it gif or jif, it’s people saying that pronouncing it the other way is wrong. Both are acceptable.

I can’t for the life of me find it now, but the gif was introduced with an image that contained in its metadata a statement that “it’s pronounced jif”. You can still find it somewhere and open it in notepad and read it for yourself.
