Maybe CZ did outplay SBF, but aside from the optics it doesn't seem anywhere that salacious. As was summed up earlier today in an NPR segment on this story "airlines don't compete on safety." In other words, it is in the interest of every exchange that the exchange industry is on the whole viewed as being comprised of trustworthy actors. Crashing FTX doesn't seem an optimal move given the already precarious state of the crypto industry these days.
Speaking of optics, the author also made a nonsensical analogy "more opaque than a dog with glaucoma" when describing the inner workings of FTX. Quite certain they meant cataracts – the clouding of the lens of the eye – not glaucoma, which is damage to the optic nerve.
