You might not care about it, but a lot of us do. Nobody is trying to convince you to stop using Plex, we're just trying to explain why we really do not want to use it ourselves
No you are not. This thread straight up opens on "why would anybody use Plex" and this whole branch is about how people don't want anybody using Google for login.
You are presenting a lot of great hypotheticals and I'll be happy to stop using Plex if and when they stop being hypotheticals. They are, though, so I don't particularly mind.
Especially because we've moved from "oh, maybe get your family to not use Google to log in" to "actually, get them to move to F-droid or install from source and do so under proper DNS filtering to stop telemetry gathering".
Friend, if people's relatives were willing to install their Plex client from source they wouldn't need anybody to host a Plex server for them. What the hell are you going on about and how detached are you from how people use software?
I swear, online... man, "posers" is so harsh, but I can't find a better word. They always pretend they are running some top secret off-the-grid operation like big corpo is coming after them specifically. Your data is probably not that tightly kept (mostly because a bunch of it probably doesn't depend on you) and it's not that much of a priority.
Oh, and while I get that you get a kick of repeating what your understanding of US law is at me, over here backing up to additional media is explicitly supported by the right to private copy. As is, implicitly breaking DRM.
Not that it matters because nobody is enforcing these at individuals for private use anyway because the rules being sought are absurd and holders know it and they just want scary tools to wave in front of individual users and to actually deploy against major sharers. You are playing out this weird scenario where a company goes to Plex to get your name as if Plex doesn't have a business built on helping you do the thing you think they're chasing you for and has a ton more money they could be sued for. It's nonsense. The reality of it is it makes you feel cool and savvy to secure your home computer as if it held state secrets.
And that's fine, but don't act like anything else is insanity. It's kind of obnoxious.
