Paul said they'd have "been fine" with Sam staying, which is different than wanting him to stay:

> For several years [Sam] was running both YC and OpenAI, but when OpenAI announced that it was going to have a for-profit subsidiary and that Sam was going to be the CEO, we (specifically Jessica) told him that if he was going to work full-time on OpenAI, we should find someone else to run YC, and he agreed. If he'd said that he was going to find someone else to be CEO of OpenAI so that he could focus 100% on YC, we'd have been fine with that too. We didn't want him to leave, just to choose one or the other.

It's interesting that YC had to raise the issue, rather than Sam saying to YC, "Hey, I've found this other thing I want to do full-time, can we start looking for my replacement?"
