You are saying many things about the legality of this, especially internationally and regarding what Plex is or isn't obligated to do, that are a bit of a stretch. But man, are they put in context by the admission of left wing cosplay there at the end where you concede you do think "a little bit of crime is good, actually", which explains a lot of the hack the world mentality and why you feel so cool and dangerous by sharing some torrents you got with a slightly larger group of people than your direct family.
I still do think that's counterproductive if you ever want a scenario where the late-capitalist media distribution landscape gets at least a modicum of competition from more reasonable and sustainable alternatives. That you prefer to feel edgy than to propose a viable scenario for that is all well and good, but I wish you didn't feel the need to do that at people.
For the record, you are still wrong about SSO. Again it makes sense that if you're cosplaying cops and robbers "this thing bad, this thing bad, both together worse" sounds reasonable, but if you really were at risk of any real legal liability that's really not how that would play out. In the real world ANY leak of that information from any source would be an absolute problem. So the Google login could be a problem by itself, and the Plex data gathering would be a much bigger problem by itself, but both together would just mean you are exactly as screwed as with just one.
But you think it's cool to crap on Google (which I guess it is) and are cosplaying, so that's a cool thing to perform outrage about even if it doesn't really matter in this scenario. Which I'm increasingly realizing is all this conversation is about, from the "I'm so good at networking and system administration" braggadocio to the "I'm such a dangerous anarchist criminal that doesn't give a crap about the rules because I'm so good they can't catch me" stuff.
FWIW, I do care about self-hosting as a viable commercial alternative and about a legal framework to support it, but even if I didn't think it was possible (which it is, and some people at least are working along those lines) I am not ready to give up on the changes required to get there just to feel cool on the Internet. You do you, though, just... try not to scare the normies away. Not that there are any normies around here anyway, so I guess we're safe on that front.
