It does not work that way (logically). Listing a 100 weak, baseless arguments is a debating tactic to confuse your opponents, not allowing them to address and debunk specifics (and if they still manage: "The lady doth protest too much, methinks"). It also creates the appearance of smoke.
More likely: There is a activist political trend now, that has picked up a lot of steam. In that political view, society is racist, and whites at best profit from this, at worst contribute to this. Anything bad happening to a person of color is then used to accuse the racist system, or even individuals, of a heinous act, to force their hands to adopt your view, or deplatform them and their criticism as an obstacle to growth of your movement, for personal gain, as revenge for inequality, or as a coping mechanism.
Far easier to argue/reason/imagine that, than that Coinbase makes WFH exceptions due to skin color, or that black employee are correctly assessing skills and experience of co-workers and correctly identifying racism on skin color, when passed over for a promotion. And if you don't believe that racism is really a driver at Coinbase, the correct course seems to be to attack these allegations for what its actually doing, not to support it by falling victim to this poor-argument overload and resigning because it is too hard, or too sensitive, or too taboo, to call out this damaging and horrific behavior.
