If you scroll down to Torleif Stumo there’s a quite interesting story. I was amazed that an aircraft that started to taxi returned to the gate and reconnected to let a passenger exit who discovered he was on a 737 max -- and that the airline rebooked him at no extra cost. Then I realized after my speed-reading what I missed: this guy was the brother of a passenger who was killed in the Ethiopian Airlines flight. I wonder if it was Ethiopian Airlines that he was gave him the extra sympathetic treatment.
The article starts with another passenger demanding to exit after the gate disconnected, upon finding he was on a 737 Max. They omitted how he was treated w.r.t costs. I’m sure all airlines probably have in their contract of carriage a clause that allows them to change aircraft and presumably the passengers have no rights. I say that because you aren’t even guaranteed a layover. E.g. if your ticket is from New York to California via layover in Vegas, and for whatever reason the airline needs to reroute you last minute connecting in Detroit instead, the contract of carriage allows them to make changes is substantial as that and passengers have /no rights/ in that regard so long as the airline reaches the final destination on the correct day.
