A friend of mine uses pay-as-you-go Oyster and regularly takes the
Overground from Kentish Town to Stratford, and then continues by
Underground from Stratford to Gants Hill. *She claims that, while making
the intercharge, she has to touch in at a red Oyster card reader in
Stratford or else she gets overcharged for her journey. *Is this true? *If
so, why? *Why can't she just touch in at Kentish Town and touch out at
Gants Hill? *There isn't some more expensive route between the two stations
that she has to prove she didn't take, is there?

Yes: Kentish Town - Bank - Gants Hill

*Is this "touch in at
interchanges" policy just a hoop TfL makes people jump through in hopes of
making money off those who forget to do so?

No, it's a way of allowing people to choose between an expensive
journey via an expensive route, or a cheaper journey via a cheaper
route.
