Upgrade != replace with something new (like using another OS or whatever)

Backward incompatible change means there is cost associated. It is like changing your furniture every 6 months. New furniture is fun, but unless your needs have changed (like marriage, children), it won't add you any benefit other than a new look...

update/upgrade == replacing with something worse.

"because that's what you do" is not a valid justification.
