You're just getting downvoted because of your phrasing. You sound like this isn't a problem because people can use adBlock. I think most people who downvote actually agree that his is an efficient counter measure.

That’s great if you’re on the web, but as far as I know there’s no way to block on ads on a native iOS app.

You really don't need an app to read a newspaper.

I use the app "safari" to block ads on the app "nytimes.com" and it works perfectly.

Pi-hole should. It blocks the ad servers at the DNS level.

Network Level ad blocking.

PiHole or some other solution to block things at the network level. PiHole is basic DNS, some firewalls will give you ability to actually block the traffic using IP Lists.

The ads often crash the app on my tablet and occasionally my phone too. I've taken to refreshing the content and then switching to airplane mode to cut off network connectivity. You don't get images but you can read all the text as articles are downloaded to your device.

I find videos still autoplay on iOS even though I have an adblocker and iOS supposedly blocks auto-play videos.
