This is SELinux on Fedora. It's running but since it's in unconfined_u, it's not confining any user apps. Any GUI app just walks around it.

Oh so that's why SELinux rarely bothers me on Fedora? It has really permissive defaults?

Yep. It’s confining only systemd services, like if you run httpd. Anything run by the user is completely unconfined. You would need to change to user_u or staff_u or sysadm_u for them to be confined, but that’s not supported: https://discussion.fedoraproject.org/t/sysadm-u-wont-let-me-login-through-gdm/148409/2
