For Reddit: If you really want to participate, use a third-party app like Infinity but with your own API key. That's easy to setup, you just have to follow this tutorial.
If you don't want to participate and just want to see Reddit posts without using the app or the website, use Redlib (the link I shared uses redlib btw)
For YouTube: Either replace the app with another front-end like Newpipe or only use YouTube in a browser (which would still not be private but it's slightly better than using an app). You can also use Revanced but I don't know much about that one.
Trump is ONLY bringing us THE FUTURE that George Orwell showcased to us in 1949! That's 60 years ago! ABSURD! We were supposed to get this in 1984!! Thank you, President Trump!
