I hear what Elijah_Baley expressed in the OP post from a lot of people. The feeling is that Plex is reaching out into new areas but doing so at the expense of existing customers. They see work done on PlexAmp, VR, News, Podcasts, etc as lost dev hours that could have been used for the core features that are lacking or feel unfinished. Certainly that is a valid argument as well as the reverse that several different teams can be working on different things at the same time, but of course all development has to be paid for, so the real question is where the money should be spent in development. 
I think most people would see the “News” as lackluster and probably don’t use it much if at all. The people I talk to would rather just go to CNN, Fox News, FaceBook (ick/yuck for news), insert favorite site, to stay up to date on news if they want it. They get to pick the journalistic sites that appeal to them with or without bias.
PlexAmp is seen by many as nice, but to little to late. It’s seen as 10 year old technology delivered late in the life cycle of the product. It’s counter productive to the way many people use music these days. We used to have to own or have the music to load on our MP3 players or smart phones. Now the majority of music people use services like Spotify, Pandora, Slacker, Tidal, Amazon, Google, Apple, etc that host the music and allow us to search for our favorite artists or similar artists/music without purchase of specific music. Users of these services usually don’t have big music collections because they don’t need or want to. PlexAmp does bring some nice improvements to music listening but unfortunately are limited to that one client and not available on the devices most people would have hooked up to their audio system. So for many it’s another “near miss”.
VR is quite a niche product. It’s certainly not a feature the masses of Plex users are going to use. Let’s just leave it at that.
Podcasts are arguably more useful then anything mentioned thus far. Like the online music services, Podcasts have been the “other” radio killer. We are no longer at the mercy of the radio station programming department. We can pick and choose what type of commentary we want to listen to! Podcasts while still very functional, is morphing in new directions and uses each day. There are now tons of channels on Youtube that are both audio and video and essentially “video podcasts” but on a different easier to use medium. They are way easier to monetize and find (embedded in other web pages, search results) for people as well without any special tools which is a prime reason people use them.
People who do use Podcasts tend to use specialized tools and directories. I know I personally D/L the content vs streaming so I can use them in the car (no data usage) or while cutting the grass where WIFI won’t work well, etc… I can add a podcast from anywhere on the web by hitting the RSS link to add it. I don’t see myself changing my podcast use over to Plex since it won’t have the feature I use (yet) like syncing or video support. I’m sure I’m a more advanced user (but aren’t most existing podcast users?) then is targeted here. However, with that said Plex will expose a lot of new users to Podcasts because they have made it easy with a basic set of features and decent default casts.
Personal Opinion:
I’m not really pro nor con on these services themselves. What I’m not happy about is the way they are implemented. I’m not a fan of giving up control over my users and what appears to come from my system. I don’t like features like NEWS, PODCASTS just showing up on pages with my content on them. This has been hashed before on the forums. With each new release of a feature not running on my media server this issue becomes worse. It’s MY SERVER, MY SERVICE, MY USERS and I want to control the PROGRAMMING of what info is available when someone is connected to my server. This is what Plex doesn’t get or will argue with. These are NOT Plex users, they are MY users. This is something other software providers do understand and value.
There are tons of Podcasts that aren’t appropriate for some audiences or young kids and admins of systems shouldn’t have to jump through hoops to turn off said features or give up control (we have) of this. Any user with a Plex Account can turn on/off these features against the will of the admin. While this is probably good for Plex, Inc. it’s bad for the admin and a step in the wrong direction or evolution of the product IMHO.
On the Flip-side. I may really love Podcasts & News and want it to function just like one of my libraries and seem like my server(s) have a lot more content then it does. Why can’t I do this? I think a lot of people would prefer EASY control over these new features. It would make it easy to not “share” features with kids but to share them with adults for example, or remove said feature when someone calls YOU (not Plex) up for support or to complain. I could then tell them to go pound sand, remove them completely or just remove said service BUT it’s my decision, not someone else’s. Surely if I nuke the user, their use of any Plex software just halted and they won’t be using it anymore for News or Podcasts.
For me it’s about control of these new features and what comes down the road similar to them. Plex used to make it easy to control the content and what is/isn’t shared with people but are throwing this away. This type of functionality/control still would not be hard to change and should in order to make a better product.
I personally would have no issue with Plex releasing a streaming TV subscription service like many others, mini Netflix, a music service, etc but I want to control who has access to such services when the user is connected to my server. Is that to much to ask for?
