It would be helpful to be more upfront in the video about why Facebook is tracking this, because it looks like it's Facebook Analytics for Apps - (https://analytics.facebook.com/get-started/Apps#fq), which puts this on par with Google Analytics for Apps - (https://developers.google.com/analytics/solutions/mobile) in terms of problematic behaviour.

So it is unclear if this is data that is provided to Facebook servers but not accessible to Facebook, similar to options for Google's Analytics platforms, or if it is harvested by Facebook by permission of the app creator. Both options being shady, as it's not told to the user, but this video feels more like it's saying Facebook is actively tracking people, not App Designers are giving Facebook permission to track you in exchange for marketing analytics.

The data that is being provided is significantly too high, and the user should be made aware, but this video seems to only discuss it being API calls to the Analytics interface when using the app. I'd definitely expect there to be API calls when using an app, but how User ID tracking is done is probably the most potentially dangerous part here.
