Good to be aware of but doesn’t really work. Ignoring the grey area of “within the airline’s control” being the kind of mess that is not worth fighting: The solution is “We’ll book you on the next available flight”. Which is already potentially the next day but also quite likely to break any connections you have.
As for a monetary refund? They are only required to do that if
you were informed of the delay or cancellation 14 days or less before your original departure time
you arrived late at your final destination by 3 hours or more, and
The former is already handled. And the latter is the three hour window that was mentioned.
