They make this monstrosity of a mouse to go with it, https://www.8bitdo.com/n30-wireless-mouse/

There’s risk in that. Unless you go through a bunch of other steps to hide magisk, there’s quite a few apps that will stop working or flag you just for having magisk, and some games may even ban you from playing. Namely Pokémon go.

No one makes something that runs one single app.

How does this apply to this situation?

FOMO?
