...thus raising the bar for privacy-preserving techniques in client side browsing. Aggressive fingerprinting arrived years ago; if we can move beyond cookies altogether and focus on it as the next issue to tackle, I would think that's a net win. Saying that we should keep 3rd part cookies alive and healthy because it will keep websites using them against users rather than fingerprinting is just throwing the majority of users who don't know to block them under the bus. Plus it still leaves the door open for even privacy-conscious users to be defeated by fingerprinting anyways if a server is keen on tracking particular individuals.
Yeah, the only way third-party cookies will block creepier fingerprinting crap is if the creepy stuff is prohibitively more expensive.
But once anyone gets a creepy fingerprinting system working, the barriers drop, and it becomes cheaper to resell the capability as a library or service.
It may offer some minor benefits in terms of enabling companies that "want to be more ethical than the competition", but that too seems like a long-shot. :p
Fingerprinting defeating technology is just the kind of thing that I wish Firefox spent its effort developing instead of reimplementing features form Chrome like tab groups.
