Agreed. Continuous updates are unnecessary if you have sane restrictions on your system, i.e. strict firewall, limit software being installed. Probably the only exception to that is the web browser itself, but even that can be mitigated to an extent by running with an ad blocker and javascript off by default.
Not only are they unnecessary, they are often best to be avoided. I recently had to reinstall Windows OS after I updated firewall software as after that VPN stopped working and some serious IT pros were not able to fix it (even with different clients tried). After we lost a couple of days, I reinstalled OS.
