FB is as public as it gets too (in addition to being a Publicly traded company).
I think speaking honestly without legal jargon, beating around the bush, simply stating why she's in it is a good look.
Pure. Honest.
Didn't even say "We're 100% going to succeed" a bit of humility there. That's a good thing. Still going to give it their all, and have the pieces (it appears) to make a good thing happen for all.
