Hi Emil,
The reason that the content is restricted is because this setting for pages is disabled(http://take.ms/4Le5n). Once you enable that, that stream is no longer restricted, and admin posting will also appear in pages.

If you want to hide the admin stream in the dashboard main stream as well, you can enable this setting(http://take.ms/XOoU0).

The pages stream differ in the examples above.
Not showing as user but showing as admin.

The reason they differ is because they are 2 different stream items if you refer to the stream id in the url.
