This exactly.

I looked into setting Plex up a few years ago. It installed, and then starts talking about making a cloud account. I don’t want to talk to a cloud I just want to organize my own shit on my own network. Why does that need a cloud?

I uninstalled it. Everything I’ve seen since, and I mean EVERYthing, tells me I dodged a bullet. Not once have I read an article that makes me wish I’d continued the install.
