Still doesn't block ads from the Facebook mobile app.

Even if you install a root cert to MITM, some apps pin certs.

Of course, there are ways around this: you could make a copy of Facebook that doesn’t pin certificates.

True. Not for iOS though, atleast without a jailbreak.

If you have persistence, no jailbreak is needed. Would require you to binary patch the executable then resign the binary using your own Apple Dev account. Far from trivial, but still doable and without Jailbreaking.
