Correct - DVC is not an abbreviation, but it is also not an acronym - it is an initialism. To be a true acronym (which is a subset of all initialisms), the letters have to form a pronounceable word. Hence RADAR is an acronym, but FBI isn't. Additional letters from single words are sometimes used in order to make an initialism into an acronym. The word acronym itself is a fairly recent invention (within the last 70-80 years) which is a combination of "acrostic" and the Greek combinatorial suffix for word - "onym".
As for DVC, you'll have to take it up with Rich Lucibella if you don't like it being used here.
