How do we feel now about having pointless services listening for no good reason on open ports?

And do we feel about running no firewall?

For example Linux works totally fine without running dhcpcd and without running avahi. But on many systems where people think they run "no service", these two shall have ports open on your network and happily listening.

Sure, it's typically "only" on your LAN: but how long before we see exploits affecting even private LANs?

Tighten your stuff up guys.

I think you'll find that for most people, plugging the laptop in and having the network immediately available and automatically seeing their local printer is a pretty good reason.

This CVE has nothing to do with leaving random ports open. "Tightening up" will not protect vulnerable servers.

how you refresh dhcp lease if there is no service taking care of ? Why you think DHCP is pointless ?

		Use a static up when at home. I would agree it’s a bit pointless though.
