Also that suggests another angle. Someone has an incentive to slow the spread or discredit it. Financial advisors in this case.
I believe it's much more about this: incentive to slow. True here, with Weinstein (people afraid or benefiting), with Trump being unhinged (Republicans in House/Senate), with VC money not being the only path (VCs and those who want to work with them)
