They are not open source though; sorry I didn’t see the sub.

HDO Box, Onstream, BeeAnime are quite good. You don’t need debrid or a VPN for them as they’re not torrenting.

If you’re using this laptop to do work, then Mint or Zorin can’t be beat. They have user-friendly interfaces, they have stable packages meaning updates are unlikely to break your OS, and you can still install new software through Flatpak and Snap.

Once installed, install Librewolf for web browsing, VLC for video playback, OnlyOffice for MS Office files, and any other software you need from the built-in software store. If you choose Mint then you need to turn on unverified Flatpaks in the software store for everything to appear.

Also, with the original 1 x 4 GB of RAM and mechanical hard drive, this laptop will be slow with a modern OS, so I recommend upgrading it to 8 GB RAM (2 x 4 GB is recommended for dual channel speed) and an SSD beforehand.

Use a VPN with a circumvention protocol like Stunnel. Windscribe has a ‘stealth’ mode using it.
