I ran plex for a long time and had a lifetime plex membership. They pushed their services so hard, but I let it pass until they stated emailing out to all my friends what I've been watching.

They violated their promises. They stated that they didn't track or know what people watched. This is absolutely a lie. They have to track it to email it out to friends.

I deleted my account, destroying my lifetime plex pass and moved to Jellyfin. Yes, it's not as polished, but it preserves my privacy and I don't get ads filled free crap tv shoved in my face all the time. Plus Jellyfin generally does just work. I don't miss Plex at all.
