The EFF is neither right nor left wing, they advocate for privacy and freedom. Free speech includes speech you may not like, and it certainly includes things I do not like. Luckily one of the freedoms generally included in “free speech” is the freedom to ignore, shun, call out, shame, etc. those who say things I don’t like if I so choose (like what you are seemingly trying to do with this post, in fact).
I switched from Plex to Jellyfin several years ago and haven’t really looked back. Overall I just didn’t like the direction plex kept going (pushing shit streaming services, central auth, paywalling features), and dropped it even though I grabbed a lifetime plex pass back in the day. The only thing I miss about plex was the ease of developing a custom plugin for it since you could pretty much just drop python scripts in there and have it work, though their documentation for plugin development was terrible (and I think removed from their site entirely).
