I don't know, but I see unnecessary all caps in other words too - it's not infrequent that I see JAVA and sometimes RUST (for the programming languages). Kind of irks me, but obviously doesn't really matter. Ultimately I think it's just a weird niche cultural holdover from the very early days of computing when lots of random stuff was arbitrarily capitalized, like FORTRAN was originally all caps, maybe related to early character sets that only had capital letters.
