Given that Sam has acknowledged that he spends most of his time on OpenAI already, and this article mentions that he hasn't been involved with the operations at YC for a while, this sounds like a case of the org chart catching up with the existing structure.

I wouldn't be surprised if this indicates few, if any, changes other than formally removing the CEO title. In light of that, it's possible that they tried to downplay the public message because internally not much has changed and it truly isn't a big deal.

This is pure speculation, of course.
