The author does not _want_ to download an app because it is "antisocial use of public bandwidth". What exactly is social use of the bandwidth then? Is this kind of attitude common?
I'd be very uncomfortable downloading an app on a foreign network simply because a single web page told me to do so. I'm sure I'm more paranoid than most, but that's an easy way to get phished. I'm surprised the author didn't cite that as a reason.
