I don’t disagree.

There is one forum I still participate in:

https://forums.whirlpool.net.au/forum/

It’s mostly tech-focussed and Australia-centric, but it does have other topics like sport, TV etc…

I wish there were more like this.

I hate that the bulk of online discussion is now owned/monopolised by a couple of huge corporations.

I’m not the OP, but I had wondered the same thing. After already seeing up the other *arr’s I couldn’t work out the point of Prowlarr.

Re your comment about resource constrained, I have just started using Sonarr and Radarr on a Pi4. They seem to work OK. Had installed but not set up Prowlarr yet. Hopefully that wouldn’t slow things down if I used it to sync the other apps.
