Apple has removed several ad-blocking apps from its Store that created a risk of "man-in-the-middle" security breaches. While Apple now permits ad-blockers for Safari, the banned apps also block ads from native apps by installing their own "root certificates" and shunting all traffic through a VPN. From there, they read the unencrypted traffic and remove ads, provided you enable the feature. As spotted by Techcrunch, one of the apps Apple removed was "Been Choice," software that even removed ads from Apple's own News app. However, it was also gathering "behavioral data" and sharing it with other companies, offering users points and cash rewards in exchange.
