Some sources say not to change transmission fluid While others indicate that you should. What is the truth?

A friend of mine shared with me an article that said for a Toyota RAV4, in the owner’s manual, it’s specified that the transmission fluid should not be changed for the life of the car and should never be drained but the dealership was telling him that it should be changed. I’ve seen conflicting sources on either side saying change, don’t change. What’s the actual truth here though?

I have a 2010 Toyota Prius and some people say that the Prius has a special CVT transmission that should not be changed for the life of the car…
