PolyMC had some drama a while ago with a hostile takeover by a dev. The other original devs forked it and are now continuing the development at Prism launcher

Nice guide! However, I’ve always wondered if all of these even make sense. Like, can’t you just stream from the internet? I understand having thing on your physical storage device is an extra degree of freedom but it’s very rare for me watching something more then once. Also while you can technically run it off a Raspberry Pi, it’s not really recommended and you would need a separate PC which just adds to the cost. Meanwhile, with a simple app like Cloudstream, you can just get whatever you want whenever you want. The only advantage I see of the *arr +media server approach is not needing to connect to a VPN.
EDIT: After reading the replys just realized I should have specified by streaming sites I mean the shady ones, in my country we use different words and I see how that can confuse some people
