"Change for the sake of change" is an assertion that one cannot corroborate, and is likely informed by one's bias in favor of keeping things at the status quo. And, anyway, if the reason for doing something in a particular way is no longer required or valid, then ceasing to continue doing it that way does not rise to any reasonable definition of "for change's sake."
"Tried and true" is a crutch, and "that's the way we've always done it" is most often used to justify doing something stupid. Like wearing white jerseys at "home."
