I have a buddy using The Players Klub.
https://troypoint.com/how-to-install-the-players-klub/ It costs $8 a month but in the two months he has had it it has worked flawless.
My buddy is a tinkerer, with all the android TV streaming boxes, I thing he has 8 now.
He has tried all kinds of streaming services, most of them free, but for $8 his advice is
get it. It has the best user interface, lack of pixalization, no down channels.
As to whether it's legal, I'm not sure who is legally wrong the provider or the user, if anyone.
What streaming box, I'm happy with the Amazon devices, Fire TV stick, Fire TV Stick 4k, or Some like the Fire Cube. I don't have that, my buddy did, but Alexa was too intrusive, always listening.
I now have an extra FireTVStick, when I visited my Daughter, I took it, just so I could watch Foxnews. Worked fine. btw that was using an APK called Modbro.
