No, this is exactly what he said, laid out in argument form:
Premise 1: Tech companies are often accused of racism (any, not coinbase, neither of us mentioned coinbase)
Premise 2: Tech companies often contain a much larger % of Asians, a minority
Premise 3: (implied) having a disproportionate % of any one minority makes you non-racist
Conclusion: Therefore Tech companies are not racist
The conclusion does not follow because premise 3 is wrong. You can be racist about other minorities even while enthusiastically supporting one minority group.
