The amount of money lost when millions of small restaurants and other retail shops suddenly become unable to accept customer payments for an unknown amount of time because Microsoft thinks Windows should force update during rush hour rather than allowing the computer owner to wait until closing time, would seem to be far greater than the amount of money lost with once-in-10-years WannaCry attacks

Don't you get out of forced updates if you set yourself regural update point ? (e.g. every Sunday night)

Most users, for better or worse, don't want any update ever, unless they wish for a specific feature. We're at a state where there's only once-in-10-years massive attacks exactly because of mandatory security updates that will be forced on the user if they have no intention to install it ever.
