I don't know how recent that statistic is, but the statistics Duolingo released a few years back were misleading. I believe Duolingo claimed, for example, that Swedish speakers were most interested in learning Arabic, but they left out the fact that they only offered one course for Swedish-speakers aside from Arabic.
My thinking is that it takes a certain personality type to whistle-blow, or push back against SOP for moralistic (or customer-focused) reasons. I don't want to overplay my hand here — I don't know for certain — but Coinbase's current messaging strikes me as off-putting to that sort of personality type.
I think Coinbase will now attract/retain fewer conscientious employees. The kind of employees who definitely won't leave are the ones with careerist/mercenary personality types. If that becomes a vicious cycle ( per the 'like attracts like' thing https://youtu.be/wTgQ2PBiz-g?t=75 ), the culture could lead to wide-spread ass-covering and fraud.
Then again, this isn't an area in which I have some particular expertise. Maybe it will work out perfectly.
