The idea was that admins don't always keep track of the new content types and don't visit the hub so often. Authors do, so we show authors that new content types and updates are available, and they tell their admin. This has worked very well according to plan since we got complaints from admins all over the world about all the update and installation requests they are getting from colleagues eager to get their hands on new features.
The idea was not to create problems for admins, and it seems a number of requests they get because of this can be a real problem in many organizations, and some even turn off the hub to reduce the amount of incoming requests to their IT department. That is why we're changing our minds and we'll have to find a new way to notify admins about updates.
1. A user won't see restricted content types if he can't use them.
2. A user won't see not installed content types if he can't install them.
3. A user won't see update buttons if he is not allowed to update
