Most in-app Ads can be blocked with simply changing your dns.

And most people don't even use adblocker when browsing normal site. I kind of had to tech my surrounding people to use adblocker.

Isn't that a much higher bar for most people? I don't even know how to change the dns on my phone, and I am not a typical user, I am a dev.

But running a browser that blocks ads like duckduckgos is super simple.

But yeah I am sure there are additional tracking and possibly retention benefits.
