It’s my goddamn motherfucking mobile data and MY PHONE. I should be able to use it however I want. My wifi went down because the greedy, cunt-faced shitbags at Comcast stole taxpayer subsidies to enrich themselves instead of actually providing the service we’re paying for. I tried to switch to a mobile hotspot and my phone refuses to open one. Everyone responsible for this shit should be fed to alligators locked away in a fucking gulag. We have no rights and live in a corporate plutocracy.
Rooting and custom rom get interchanged a bit. Rooting just means gaining access to root, graphene os is a custom rom and you don’t necessarily have access to root. Personally i’ve been running custom roms for years with no root but it’s my property and damn sure better be able to root it if I want to. Anyway, with either root or custom rom you can probably get around your carrier’s tethering restrictions which is what OP meant.
