I’ve been burned twice with FCP. Happy on version X, updated macOS, run FCP and it fails with that it doesn’t work on this version, contact FCP and get told I have to pay for the latest version to work on that version of macOS. It seems like it’s just a version check. If it was a major version upgrade I would happily pay it. But even premiere pro never broke between OS version updates on macOS or windows. So it seems like a FCP thing.
