That's where the X509 certificate comes in. A man in the middle
would not have the proper private key to impersonate the Facebook
server that the certificate was issued to.
Supporting TLS in their case is not good enough... they would need to
force all connections to be over TLS, to achieve security against
As soon as an app causes the end user to switch to a non-TLS
connection, they are vulnerable.
