You set up a node on some other server and enable it to be an exit node, and can then access the Internet through that one. So any node on your net can be your VPN exit point at any time, if you want to juggle several, for example

I’ve got both a fire TV stick 4k and acorresponding Mi tv stick, both mainly for jellyfin, and would recommend the latter. Basically same price, both work fine for the purpose but fire has their ads on the home screen whereas Mi is more clean and has the Google play store, making some things easier to install. The Mi apps you can just disable.

They have free licenses for students, but otherwise I don’t think so
