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.

Does Facebook Analytics for Apps segment the data from that of Facebook or combine it? Is there any policy even stated that says it's not used for other things. I would suspect, but have not looked, that all the data is combined together and used for selling ads and in other ways.

If that is the case, an app that is using it to get analytics for themselves is also sending lots of data to Facebook to be used for their other purposes.

Is this information transparent to anyone? This can lead to the tracking failing GDPR or other laws.

Now, if it was only analytics for apps for the benefit of the app owner and not shared... things might be different legally speaking.

Of course IANAL and they may have much more to say.
