In a campus/managed network we default block port 80 outbound from web servers for this reason... we wouldn't want the option for the host/server to undo this.
A SOHO enviroment may - or may not - be different.
How would it make sense for a home gateway / CPE to refuse incoming connections to port 80 even though the person who is paying for that box wants those connections to happen?
(And consider that that person may very well posess a screw driver.)
Another example might be the classic port 25 smtp outbound filtering.
This type of filtering happens in the ISP network, not the home gateway / CPE.
