The reason this is related to browser fingerprinting is that cross-site cookies aren't _just_ used for CSRF, they're also a way to track users across sites. With this change, developers will have to _explicitly_ declare when they're using cookies for that purpose (by setting SameSite=none) which makes it easier for browsers to identify cookies used for tracking and give users control over them.
