There does seem to be a strain of weird language fanatics who insist all programming language names must be shouted, so they'll write RUST and ADA, and presumably JAVA and PYTHON, maybe it's an education thing, maybe they're stuck in an environment with uppercase only like a 1960s FORTRAN programmer ?
Similarly, and less explicably, are people who program in "C" and don't understand when people mention the oddity. Do people not see quotes? Do they just add them and not realize?
It's funny because Fortran's official name now is Fortran, not FORTRAN.
Maybe who cares?
You, apparently.
I have found a strong correlation between people who say JAVA and country of origin. And thus have assumed it's an education thing.
