Or, it's someone who the SaaS vendor forced to click that button by putting OIDC ("Sign in with..." or "Continue with...") behind that, using "SSO" as a price discriminator.

Right. The phenomenon is real, but the description on that site seems a bit obtuse on purpose:

> For organizations with more than a handful of employees, this feature is critical for IT and Security teams (...) In short: SSO is a core security requirement for any company with more than five employees.

No, it isn't. They'd like it very much, but the SSO tax is proof positive that this is not a truly critical feature for small customers. In fact, it pretty much measures at which point it becomes critical.
