They won’t, at least not for now, I assume. They can put far more intrusive tracking inside an app compared to a web browser. There is also no way to do content blocking or ad blocking inside apps, at least not on iOS. I use Facebook in Safari - can’t be happier (well, I mean it’s Facebook, but I am not able to pursue all my friends to cancel it).

You can use a adblocking DNS server. Either a pi-hole in a VPS you control, or something like NextDNS (which I am really happy with).

It doesn't block everything, but almost nothing is getting through for me.

With the shift towards DNS implemented at the application-level as DoH gets rolled out, apps will ignore your adblocking DNS servers.

I am starting to believe this is why Google is pushing aggressively for DoH...
