So good, but a little naive like me
That is the best message to Yaniv - outlines all my concerns (and then some!). However, do NOT expect any useful response. I messaged Yaniv something similar, and his assistant's response to me was "thanks for the advice." Which was weird, because my message had questions. I even sent a follow-up email, and still no response.
I hate to say this, but the only way to get across to him is via an aggressive, borderline threatening manner. Threaten to escalate to SEC - he'll pay more attention. But for now, give him the time to respond - who knows. Maybe things have changed in how they respond to inquiries now that Dror is gone.
