4. DLNA Support - In-House Streaming Music/Video Content
No, you shouldn't have to buy Plex to get a function that was on the previous hardware to work properly. Again, it's a business decision born from the realisation that they gave it to us a little too easy last generation. Sony's Music or Video Unlimited services (the former of which is about to be replaced with Spotify) are what you're supposed to be whiling away the hours on instead of just plugging in or streaming your content in from the device in your lap. However, like the custom backgrounds point, you can't remove functionality we previously had without backlash. It's fine to iterate and remix things going forward, but removing something people had on an older machine just brings about similar debates like when things Apple split their Podcasts onto a new app, or made it so newer versions of Siri only work when you're online. Removing previously available (and working) functionality is always going to be met with the staunchest opposition possible from all directions.
