Thank you for giving the idea at least a little consideration, though,
and not outright dismissing it.

The potential compromise I see might involve exposing firewall zones in some well-considered and thoughtful way, including a rethink of what is blocked and allowed by the zones, and an understanding of what the goal of having each zone is. That would have to be done in both gnome-shell and gnome-control-center, and it'd need to receive buy-in from relevant designers and developers.

Such an effort would need to be undertaken by developers who understand and accept a requirement to not break installed applications or services, to not expect users to be capable of editing firewall rules, and to not require the installation of a firewall GUI application that exposes technical details like ports. It would also need to firmly reject the assumption that users know (or even that users *should* know) the difference between a TCP port and a USB port. Otherwise, the gulf between the two sides here is just too great, and there's no hope for a useful discussion or compromise. But if these requirements are OK, maybe we can agree on something.

The work would need to be undertaken by people actually interested in the problem. Expecting existing Workstation developers to work on this is not likely to turn out well, since we're busy, and I think most of us are already OK with the status quo.

It'd also be helpful to get beyond this security myth that having a firewall is somehow essential to have a secure workstation. I'm firmly convinced this is not the case, and I'm unpersuaded by most of the comments in this thread that assume otherwise. The best argument I've seen so far in favor of a firewall was accidentally sharing your Rhythmbox media library on a public network, so focusing on that or similar issues would be helpful. Unplugging from trusted "wired connection 1" (e.g. a home router) and plugging into a different untrusted "wired connection 1" (e.g. a modem) is another good example from this thread of where mistakes can currently occur. We probably shouldn't allow users to share media on a network where the user has a public IP, for instance. But just repeated claiming that a firewall is essential for security isn't going to impress me.

Iñaki seems to be batting in this direction with the issues he's filed. His approach seems constructive to me. I fear it might be easy to have missed his comment in this noisy thread.
