The app is adfree and not spammy. Can't talk about the Website though, I haven't browsed the internet without good content blockers for the last decade

This website has all the infos you need. You probably won't get anymore spoonfed than this, good luck :)

uBlock can disable cookie popups, go to settings, filters and then scroll down to annoyances. Enable AdGuard Cookiebanners and Easylist Cookiebanners

This should be the real one: https://www.luckypatchers.com/

Beware fake download ads though (I've never seen any of those, but people without uBlock might)

Try different things in the selection dialogue before patching.

If you have root you could install Modded Google Play in Lucky Patcher to automatically succeed License checks

Mods also exist to crack apps, Mobilism is a good site but be careful what you download from whom

You can crack most apps using Lucky Patcher

Make sure you get it from the official website though

iOS does not accept self signed certificates, that might be your problem

Sideberry is really good and can do all of that and much more. You need to have a custom userChrome.css to hide the native tab bar though

Jellyfin is very light when not transcoding serverside, you basically only need a decent Hard Drive and internet connection

I'm sorry, I misread your question. --cookies requires you to be logged in

Why not use TwitchNoSub in combination with Video DownloadHelper?

I always use the download helper to get the Video urls and then download them via yt-dlp

Western apps do the same

You're right about that, they're also trash
