I dug a little and apparently Chrome previously used the trust store of the platform but has now transitioned away from that to use their own. https://blog.chromium.org/2022/09/announcing-launch-of-chrom...

But even before they switched to this "Chrome Root Program", they have distrusted specific CAs, for example Symantec in 2017. https://security.googleblog.com/2017/09/chromes-plan-to-dist...
