This isn’t necessary. Maybe not even common. Forks can start as a testing ground or an experimental feature fork and grow from there.

We see headlines about the angry forks, but usually it’s just friendly differences.

The problems arise when one person wants to control the project, deny contributions, but also gets angry when someone forks the project to implement those things. They put the open source license on the repo but didn’t expect other people to actually do open source things with it.
