It's about the attempt to use a domain for personal identification that was discussed in this thread.

no, what does it take and mean to identify someone. In general and on the internet. How do you build trust? A domain is no worse than trusting any arbitrary billion dollar enterprise.

No. It's both different and worse, because you are trusting more parties for auth as well as degrading the trustworthiness in the actual integrity of the credential management by spreading it across the entire network stack in addition to trusting the same billion $ enterprise, anyway.
