> Saying “just self-host anything” makes a massive assumption that your company can afford to compete against Okta/Google for the same talent.

I have always found this argument so interesting. I host tens of services myself on a Raspberry Pi, with better uptime than many of your favorite cloud services. If a company cannot find even one person, earning a software salary, to host an open source IDP for tens or hundreds of employees, either something is deeply wrong with the company, the sysadmin talent pool, or both.
