I’m a broken record: block Google (or whomever) with network-based blocking (IP and/or DNS), these guys have third-party tracking in virtually every website and app.
Well I MITM myself quite often to confirm it. I’m also smashing together hundreds of blocklists, and I always check the network tab of my browser’s developer tools and very rarely see anything coming from third-party domains.
Sure, sometimes assets are on the actual domain I’m visiting (or its CDN) but most of the time, even tracking scripts there are broken because they still call the blocked scripts.
By the way, it’s hilarious that everyone wants to fight so hard about this yet when someone says “use an adblocker” nobody says anything as if it’s the end-all solution.
I didn’t say “I have a bulletproof, surefire way to fix this.” I said “use network-based blocking.” However effective that is is up to the person implementing it; you have no idea how effective my setup is because you don’t have access to its configuration.
Almost every B2C company I’ve worked at, I’ve written or had my devs write proxies for whatever trackers we use. The reality is that every company to whom this data matters to figure out their business model will proxy their trackers. If they don’t they need to fire their lead engineers.
It’s actually pretty easy to disguise this traffic even to the point where you can use the originating server/cdn to interleave the tracking with the content source.

as an additional measure, sure. but these blocks are not hard to circumvent, so it’s not enough in itself
They’re not hard to circumvent, sure but then why am I so effectively blocking almost everything not tied to the “real” first-party domains?
because they don’t yet circumvent it. but also, are you completely sure everything is blocked? DoT, DoH traffic and such?

Proxy? Is it that hard to figure out how to bundle and serve assets from the same domain? 😂
It’s not about serving assets it’s about hiding telemetry from adblockers, dns filters, ip lists, etc.
