There are some punctuation errors in your title. It should read:
Plex is “overhauling” its apps with a redesign and under-the-hood “upgrades”
Those who use Plex to access personal media will find that their libraries are in a
dedicated[hidden] tab, while the Watchlist will take up prime real estate in the top navigation section. Plex says it also streamlined the user menu for quick access to things like your profile, friends and watch history.
So they’re hiding the entire point of Plex deep in the menu and promoting things that make them money. Enshittification.
That’s a bold claim, not that I necessarily disagree with it. Are there groups of well respected historians that would agree that it has begun? I could only find a few here and there that think it has started.
