Absolutely, and that's why Dropbox is successful. But I don't think the part you quoted is wrong as such; the typical HN user really could put together a few components and get something that does most of what Dropbox does.
A small point really, but I'm not sure most people would only think it describes helicopters. I am guessing most people would think it is a tribe of Native Americans.
I admit that it's just a guess, but it does seem likely.
