I don't know all of the tools, do you mean the tor relay?

On Android or postmarketOS? Very cool regardless!

What would they do about it?

Does your router have webinterface where you can monitor and potentially limit network usage of devices?

I'm not too familiar with the arr stack but if it is constantly downloading videos it's probably using full bandwidth. Maybe you can also limit in the arr settings or throttle the network interface on the laptop.
