Great examples all  Since there is currently no known need for disambiguation both are probably valid  When speaking or writing about technology I err on the side of using the full name unless its really moved from jargon to a common cultural lingo  For example you could speak with the common man about DVDs but not about FVD hence the former is a direct link and the latter is a redirect  Most examples I was able to find are disambiguations of TLAs used in multiple subject areas so Im not seeing much precedent one way or the other  If youre able to find sources outside of specific industry that make use of the term that would probably help you build that case
