It is still a violation of GDPR as I as the user never have the chance to consent (or not consent!) to any data transfer to Facebook. But as no one seems to be willing to go after FB... sigh.
but that's the point: It can be. Just add that key to the plist file and the SDK won't initialize and won't do any requests by default.
This is absolutely on the app developers. Not knowing what an SDK you linked does or doesn't do doesn't absolve you from GDPR (or any law for that matter)
