Why do you pay for Paramount+ Essential (the one with ads) and then pirate stuff that’s available through it, rather than A) not pay for Paramount+ at all and just pirate or B) pay for the more expensive Paramount+ plan and not pirate?
Because even paying for the ad free service, you don't get a copy to play offline. Most of the time the performance I get from Paramount streaming is awful. Everything just works better when I stream from the server on my local network.
I also don't have to worry about my favorite shows disappearing from the service on a whim. The files on my server will always be available to me.
