The Facebook Android app is also capable of bypassing the Play Store to quietly update itself, so we wonder whether apps installed via Facebook ads would have similar capabilities. That could be a problem if a developer decides to make unwanted changes to the app, or if a previously legitimate app gets sold to a shady party.
It’s also worth noting that the Play Store has several privacy and security features in place. This includes Google Play Protect for detecting malware, a list of data collected by a given app, and a list of security measures for each app. Several other third-party app stores also have privacy and security measures in place, but there’s no word on Meta’s features in this regard.
