The push to live services, online DRM, microtransactions, DLC and other such things is because they have identified that there is more money to be made as a ‘server operator’ than a ‘game developer.’
They don’t really care about getting paid for the game, they’d rather give it away for free if they can make more money off controlling the servers.
It’s been awhile since I’ve used anything but Magisk but usually you have to set root permissions per app, or you can get Magisk notification to request access.
