Disagree. It is still a buggy mess. Many missing features that they promised. Lots of missing basic features of MMOs like no guild chat, no in game guild rosters, elevators and doors still don't consistently work, they struggle to connect the game loops, game loops don't consistently work, etc, etc.
I haven't run into any issues with MakeMKV, which I bought years ago. Only issue I ran into was some UHD discs won't read properly, but that was an issue with my Blu-Ray device. I have a new-ish Pioneer with a firmware flash and it reads everything fine.
One thing to keep in mind is there is no one official arr stack. It is dozens of mix and match services, which leads to the confusion. The very basics are the ability to automatically download movies, TV shows, music, and ebooks, as others have covered. On top of that, there are services that support the core download services. Like to provide VPN to those downloaders, automatic transcoding to other formats, automatic renaming of files and copying to specific folders, or web interface to request new content. And that is a small sample of what you can do.
They don't care. They know they'll lose subscribers but they'll make more money overall on the suckers that stick out the monopoly pricing. Same thing is happening in the auto industry where they sell less cars but are more profitable.
Aggressive? Hell no. I'm just not being Pollyanna.
