You mean SSO? I think that's slightly disingenuous because it's still possible to be perfectly secure with username/password login. Sure, having SSO might prevent Barbra from accounting (who failed the last 3 phishing training sessions) from getting phished, but that's the company's problem, not the vendor's.
When a person leaves an organisation, it’s difficult to find all the various team accounts they have been added to in order to remove them. So you end up in a situation where people no longer in the organisation frequently still have access to anything non-SSO.
That’s a very obvious, legitimate security issue, why are you accusing people of being insincere about it?

Again, that's inconvenient but doable, just like phishing prevention.

I'm not denying it's a security issue, any more than I'm denying that phishing isn't a security issue. I even specifically mentioned the possibility of employees that fail phishing training. I'm objecting specifically to the "ransom" framing, which is a pejorative way to imply that companies have a duty to offer all security features for free.
