"yt-dlp is a feature-rich command-line audio/video downloader with support for thousands of sites. The project is a fork of youtube-dl based on the now inactive youtube-dlc."
It would still be possible with native apps. Somebody will have to reverse engineer it continuously. So it will be slower, but still possible.
However, that won't be the case if they start using some secret (like a private key) that you can't access directly from an app, or if they decide that you can't run custom/modified apps. That's what I believe to be the true intentions behind their push to adopt dystopian technologies like secure enclaves and platform attestation. Not really about security as they claim.
