Nah, it was a live broadcast service. It wasn’t a common website, or a file hosting service. It was a local paid IPTV network advertised through word of mouth. Probably sold hacked amazon fire sticks that connected to an IP that was decrypting live tv signals.
Basically: buy a cable tv subscription. Decrypt all the “channels” into IPTV steams. Sell access (probably with pre-configured hardware) to the streams for an amount cheaper than it would be to subscribe to the cable tv service yourself.
