I really think everyone thinks that they are the average user. In my opinion, having the app go somewhere looking for a dictionary file is only a privacy concern if you are somehow trying to hide from any network connections. This is a far cry from Google mining our emails to show us ads. IMO, anyone concerned with this level of "privacy" should be protecting themselves through more reliable means.
But by all means if the privacy statement can be tweaked so people don't get a false sense of security, then that's great.
