Ledger had a data leak. While they haven’t confirmed the attack was due to it, the exposure of private KYC data is widely believed to increase the risk for high-profile individuals.
I agree that KYC sucks, but the co-founder story seems like a non-sequitur, how was this due to KYC?

Sure, but you don't need leak data to find out who the co-founders of a company are, and I am willing to bet that the co-founder's KYC data was not in that leak.
