There was a MacOS update that set everyone’s shell to zsh instead of the default (ancient) bash.

Hardly insurmountable, but the change was a “forced” part of the upgrade.

Changing users' default shell is not the same as forcing it on users. You can chpass(1) and set a different shell.

I'm not too comfortable playing devil's advocate here as Apple really does force shitty changes on users. But this isn't one of those cases.
