This may be an unpopular opinion but I think Rahul Yadav was made a scapegoat for all the VCs who put in too much money into housing at too high of a valuation. Yadav has his flaws -- but they are mostly childish, not evil. He gave the so-called adults a perfect excuse to hide behind but it still doesn't excuse the Board for their key decisions related to scaling, burn etc.
As for Rahul Yadav, I think he would have done well to find a person he really respects and to listen to him. Zuck did that with Andressen(no, I'm not saying he's Zuck; just that having a close mentor can really make a massive difference.) The Board could have helped here in lightly nudging him to find that somebody instead of engaging in constant confrontation.
