Plex is no longer going to allow their paying customers to opt-out of having their viewing metadata collected and used by Plex (presumably for direct or indirect profit).
Remember when it was enough to pay a company for a piece of software without them pimping out your personal information for a little extra profit on the side?
@ryanbytes I also hear it has gapless audio playback, which for some reason Plex never got.
The Emby media server looks very robust. I may install it alongside Plex this weekend and play around with it. The only thing I'm concerned about are my Raspberry Pi clients, since it looks like Emby Theater still needs some work.
