Most user apps run unconfined so this "SELinux breaks random
applications" is an overstated rumor nothing more.

Which apps fail? The majority of apps run unconfined. There might be
bugs but generally SELinux just  allows apps
to what there are supposed to do and nothing more instead of leaving
apps just do everything.

The only things that affect unconfined apps are stuff like disallowing
exec_mem and you want don't want to just allow
that for every app even if you disable SELinux.

It did.

That's a bug ...  "we hit a bug so disable it" is simply wrong we
should find out why the testing failed
to catch that bug and improve that instead.
