Original commenter here. They are not blocking GA. Apple's ITP affects both 3rd party HTTP cookies and 1st party JS cookies. There does not appear to be anything but a UI change between Safari 13.1 and 14, from my initial analysis. GA primarily utilises 1st party JS cookies. If you have GA on example.com then the cookie will be stored against example.com. On of these cookies stores a unique ID for you as a user. GA will then send 'beacons' (GET requests to Google endpoint, with data passed in URL parameters) for pageviews and other events. Your unique ID is included in these URL parameters, which allows the various events from you to be joined up into a 'session'. That has not changed. What ITP did previously (just over a year ago, I think) is limit the age of these cookies to auto delete after 7 days, meaning that if you leave a site for more than 7 days your new session won't be able to be joined up with your previous session. That is still the case. If it is of interest I have a deck [1] that discusses this (link goes to the relevant section - skip to slide 71 if you just want to understand the ITP impact on GA). I'll caveat this a bit - I've not done an in-depth analysis. The person I strongly recommend following for expert updates on this topic is (my friend) Simo Ahava [2] - he is an authority of GA and the impact of ITP.
