Bad network connectivity blocks random things too; it seems reasonable to expect any supported application to cope.

I absolutely use Little Snitch to block automatic updates of some apps that try to download updates over port 80---I don't trust them to have gotten the authentication right. I'd rather manage those through Homebrew & Caskroom.

Bad network connectivity: 1) is not permanent 2) does not block connections to localhost
