As to your other point about Londoners enjoying a fares freeze,
I'm rather astonished to learn that you weren't aware that this
freeze only applies to single journeys. There is no such freeze
on the cost of travel cards or on Oyster card daily and monthly
caps.

It's not a universal freeze, but you've got the formula wrong.

The freeze turned out to be only applicable to fares set by TfL (which
includes TfL-only singles, of course); however tickets which are within
London, but inter-available with National Rail (which includes some
singles but especially Travelcards and Oyster capping which emulates
Travelcards), have an element set by those National Rail TOCs, and
haven't been frozen.
