I don't know, exactly. It has to be something where we're confident that 
the user understands that he is about to send sensitive information to a 
stranger.

The concern isn't when this is used by a company like Apple or Facebook; 
the worst such companies are going to do with sensitive data is target ads 
better or make their products more streamlined. The concern is when some 
attacker wants to get information about your company's intranet's 
topology, or wants to know what potentially vulnerable plugins or 
extensions you have installed, or wants to know what software you are 
running, so that they can more precisely target you. Such an attacker can 
trivially provide you with a game to play, and then have the game crash, 
misleading you into thinking they're a perfectly honest game developer and 
causing you to eagerly send them all the sensitive information they want.

These are not hypothetical concerns. Over the last few years, targetted 
attacks of this nature have become much more common and are a real threat.
