Also Plex is a staple of the self hosted community (though I prefer Jellyfin.) I’m wondering if they’ve confused self hosting and FOSS somehow
That’s a very narrow definition of self hosting. Do you also not consider it self hosting if you use a cloud provider VPS? It relies on a 3rd party so I’d love to see the gymnastics that keep stuff on a VPS as self hosted but not Plex. If you don’t consider things on a VPS as self hosted then I’m not sure what to say other than I disagree.
