Is it just me, or is committing public seppuku like this really necessary? If what he did was illegal, he should face prosecution. If he's compelled to apologize and admit his guilt, he should reach out to the people he actually wronged. This kind of public self-flagellation ("I'm such a creep. Please forgive me, world.") feels really over the top, phony, and symbolic.
I think it's because he wanted to pepper in details like "It was over drinks and I thought it was social", aka actually defend his actions while renouncing them on the surface. The "upcoming discussions" with 500 associates reads like he's looking to get back onboard.
So I'm glad he painted a picture.
