It effectively is, as I had already explained, and Harald Reindl has now
Your "solution" to people disabling the firewall is like "solving" the car
speeding problem by setting the maximum speed to 500 km/h. Rationale: "The
net result of the old [speed limits] was people [not respecting them]." Now
everybody is respecting the speed limit (= keeping the firewall "enabled"),
nobody is "speeding" (= "disabling the firewall") anymore… except that all
the benefits from speed limits (= the firewall) are completely gone (because
people are still effectively speeding = disabling the firewall, you just
changed the definition)! It's the same with your firewall settings.

Because Fedora is aggressively marketing a Product with a major security
vulnerability as its primary Product.

But it wouldn't have prevented any such hole with a higher port, which can
be opened by anyone. Services running as root can and do also bind such
ports (there is of course nothing restricting root to privileged ports), so
it can even lead to remote root exploits.
