A couple of weeks ago, I published a brief article entitled, You Should Delete Facebook’s VPN App. It provided a link to a number of articles describing Facebook’s violation of Apple’s data-gathering rules. The Facebook so-called VPN, called Onavo, did exactly the opposite of what VPNs are supposed to do: it monitored everything users were sending and receiving across the VPN and collected personal information about each VPN user, information that probably was to be re-sold to companies that want your private information. After all, that’s Facebook’s business model.
Now Apple has banned the Facebook VPN from its App Store. See https://tinyurl.com/yabm7wxp.
I suggest you also should exactly what Apple did: ban Facebook’s so-called VPN, called Onavo, from your mobile devices. Delete now.
