Same deal with people talking about windows requiring new hardware really: for most people the answer should be "good, it'll stop rebooting to update now". Almost everyone is behind a firewall that doesn't allow incoming connections (it can't by default because of NAT). The only point of entry is the browser, and if you stay off the seedier parts of the web and have an adblocker, that's not really an issue either. Your bank or Spotify presumably aren't going to be dropping malware on your machine via old browser exploits.
You can't do that kind of thing if you're under some auditing regime, but they're not, right?
