I think there is also a separate debate here about whether Ito should accept or reject money from a donor who he knows is a sex offender.
Edit: seems like people are assuming he did know about that past, which is unclear to me.
According to Ethan Zuckerman, he "urged [Joi] not to meet with [Epstein]". Presumably Epstein's past was the reason for that urging.

I think that's the problem with the apology, he doesn't actually say what he's apologizing for. It's pretty clear that he's apologizing for taking money for someone he new was a sex-offender, but he doesn't actually say it, nevermind apologize for it.
He does say he was unaware of the evidence, and didn’t hear Epstein say anything about it.
