OK, you prefer to have everything firewalled by default, but what about
most people, that will be affected by default settings? (they don't know
how to change it and never will touch it; they may even not be allowed
if they are not on their “own” network, if that even means something to
them) They don't have choice: they _have_ to trust their device/OS. They
have no other choice.
So the choice is on the manufacturer: either you secure your device and
people will trust you, or you build shitty rootable stuff and people
will try not to buy your stuff (you see, they may even not have the
choice to have trust…). But asking them “patch” the security of their
device by mean of some other “magical” device (a firewhat?) is not an

Yes. But try imagining the impact on the other persons. Now try
imagining that this policy is implemented on 90% of home routers.

Yes, this kind of UI would be nice.

“Down the road” being never, as what sets the “standard” is what is
installed in the standard base. Now is time, as this release comes as
“IPv6 fully enabled”.
