I think that example really exemplifies HN's biggest blindspot. A lot of successful companies are built around taking an existing technology, then packaging it in a way that drastically reduces the frictions for the user. The typical HN user doesn't understand those pain point, because they're technically sophisticated enough that they're mostly invisible.
So, you take something like Dropbox. Yeah, it pretty much is just mounted FTP. And the average HN is looking at that and thinking "I could do the same thing with a bash script, what's the big deal".
