Setting up sonarr and radarr is not trivial, especially if you’re hooking it up to Usenet. I spend a couple of hours every year repairing the setup after the NAS has updated the mono version.
Finding the right Usenet server and the correct alternative block accounts, and then just the right search provider. Ugh. But it’s magical once everything is setup.
It's not actually that complicated. There are templates that let you deploy both in a single click on a webinterface. You can use free crawlers for content out of the box.
Various usenet providers provide you with picture-by-picture guides on how to setup Sonarr and Radarr.
There are single-click Usenet and Torrent clients with VPN integration. Just upload the ovpn file as provided by your VPN provider and you're done.
This is all either single click or explained thuroughly and easy to understand on-site or in the products FAQ/Installation Guide.
Once you have it all, you can share Plex with others, which is even more easy than all of the above. Your friends and family have access to all the movies for very low cost (up to free).
I'm new to all of that Sonarr/Radarr/Ombi stuff, but I torrented for along long time. It took me some time to set it up, granted I had to make it work with my torrent client and trackers that where already in place.
But before people can start with that they have to inform them self about usenet vs torrent, VPN yes / no and what provider, Plex/Emby or Jellyfin etc. It's a huge time commitment.
Then get it to work on your TV and phone.
Even if there is a guide to just tells you what is best, I doubt it can be done in the time most people want to invest.
The thing is, even if it's a huge time investment, if it's perceived to be easier and cheaper enough than subscribing to all the content providers (Hulu, HBO, Netflix, Amazon, Netflix and Disney+ just for TV content), people will do it.
Piracy was more complicated in the past and lots of people, even people with 0 technical knowledge did it. The only reason people stopped is because Netflix and friends made the legal alternative easier.
If piracy once again becomes easier than legal streaming, people will simply switch to piracy. It's as easy as that.
