The conspiracy theorist in me suspects that they only introduced cookie blocking after they were sure that other fingerprinting methods were reliable enough that they didn't need cookies anymore. They can pretend like they're "doing something" when blocking cookies in and of itself is another variable they can use to fingerprint you.

I read a number of martech and marketing sites (because it's good to know your enemy), and the discussions there strongly indicate that this isn't the case.

They've been spending quite a long time freaking out about the impending death of the cookie, and talking about ways to mitigate that.
