It would take the author a few seconds to type "remotely operated vehicle" (or whatever it stands for), and therefore save hours of time for people who need to look it up. Not to mention...I almost skipped the article because I didn't know what ROV stood for. Lost audience.
Your argument is that lots of experts on remotely operated vehicles would scoff at the article because it didn't use their "inside" jargon? First off, how many people would that be, compared to the number of people who love a good mystery and a good gadget, but have no idea what an ROV is?
As to bandwidth, you only have to spell it out once. Simple practice: I built a remotely-operated vehicle (ROV) and solved some cold missing person cases.
The author of this piece doesn't strike me as someone who relishes communicating in cryptic acronyms, so my guess is that it was just thoughtless. He hadn't yet seen my screed on the subject. :-)
I'm sure there are those who love communicating in cryptic code. They tend to congregate in like-minded cliques that don't much care about communicating outside their tightly-defined world. So be it. But if you want to be read and understood by a wide audience, spell it out.
