True. But the vast majority of use goes via "WWW".
For example email - the other big "internet-user" is technically not part of the WWW, but most (? I don't have any stats, just a guess) of our mailclients run on the WWW, nonetheless.
It’s the equivalent to JIT manufacturing. Cheaper when everything is going fine, and devastating when it’s not. And then when everything goes down at once there’s not enough advantage to being the only one still up.
Interestingly, server side rendered pages worked well during the outage. Most of the issues were caused by sites that are relying too much on Javascript.
