You should certainly find it questionable,

Thanks for acknowledging it.

You would not have exposed a broken firewall policy on purpose in order to
prove your point, would you ?

Wouldn't I?

I hope not.

I am explicitly describing a firewire policy for the sake of

For the sake of argument, you should have described a sensible firewall policy or no one would have taken your point seriously. The policy you described was not sensible. Here is a common one which allows outbound "connections" :

- accept outbound packets and related inbound replies
- deny other inbound packets
