Computer systems security isn't binary. It's also not a human right. Or something anyone but small minority cares about beyond the surface level.

Extra security is a feature of enterprise plans precisely because enterprises are forced to buy them by compliance requirements (a good chunk of which is just security theater and blame shifting); no one else cares, people buy stuff, things mostly do not go wrong - a market balance is achieved.

I can see why this isn't ideal or desirable, but security maximalism also has a nasty habit of killing all utility of products and disempowering end-users, so I'm very much in the camp of trading security over other concerns.

Re: security vs usability

That's precisely why SSO is so important. It's the only way to get people to use 2FA and strong passwords without compromising usability.
