What makes a network that only allows outbound HTTP different than a network that only allows some obscure protocol outbound, or a network that allows no outbound access at all? Should reportbug support DNS-based transmission to get through networks that block HTTP?
> Also, the networks in question are only "broken" if you think that every computer in existence should be able to talk freely to every other computer in existence. This model of reality disappeared (if it ever really existed) decades ago. Security and Access restrictions are not only just the reality, they are very desirable in many cases.
Disallowing inbound access makes sense for security. Disallowing outbound access (with the *possible* exception of port 25 on networks with a pile of infected spam-sending systems that can't just be kicked off the network) makes a network broken.
