And your point is...? If anything, an app that was approved for the App Store and then was revoked would make me even less likely to trust it. What issue caused it to be removed? There are millions of apps in the App Store that manage to meet Apple's conditions for distribution, so why can't this one do so?
I for one do not necessarily believe that any such app is safe to use, as the very method of installation and its requirement for blind trust of the source opens up the possibility of also installing malicious software. Note that every reported exploit for iOS has involved people consciously (but without any basis for trusting the source they click on) granting access to their devices by some URL or web site or anonymous code string.
