man, i appreciate the position you are in, but cory's behavior insofar as he calls out scammers *could* be an instance of psychological projection. deflection from his company's own sketchiness.
with respect to your concern about "best in class" custody, there are other providers with (better IMO) solutions. eg River, Strike, and Cashapp -- all of which maintain their own custody.
I love Livera too, think he puts out super high quality education, but at the end of the day, where is his bread buttered? what are the incentives of the other folks you listed?
again, no disrespect from my end, just be careful
