On the other hand, if you do it yourself you'll see all the people who block all contact between their browsers and anything they can identify as an "analytics" site. I don't have time to screw around with figuring out what uses third-party cookies, what uses browser fingerprinting, what correlates information across sites, and/or what tracks what how in general, nor to check all the time to see if any of that has changed. I'm just gonna block all of it, because it's not worth the investment of my time to make such distinctions. The most I could get out of it would be slower page loads. Actually, I'm not even bothering to make THAT decision. My ad blocker blocks GA by default, and I'm not going to worry my pretty little head about unblocking anything unless something breaks.
