问题
I am trying to get a list of posts in a particular group on facebook that is closed, also I am not the admin, just a member in this group. When I am trying to access the group's posts via graph explorer (I checked all the permissions) I am getting an empty list returned.
What is facebook's reason for not allowing this access? If I am a member of this group I have access to this information anyway via browser/scraping...
Your thoughts and suggestions are appreciated.

That would be only you being able to see the posts then, fine. Two parties involved - you, and the other group members; everyone aware of who will be able to read the posts, all good.
But with an app, a third party gets involved - the app developer. And they could theoretically do anything with that data, that the app reads from the API on your behalf. (Sure, the app developer might be you in this special case here - but that is not the normal use case.)
And in a closed group people might discuss topics that are a little more sensitive than the current weather; think f.e. health problems or something like that. For sure not the stuff you’d want exposed to any third parties.
And therefor, the decision whether an app should be able to read the group’s feed posts, has been placed in the hands of the group admin(s).

If you would like to access the data use api version 2.3, the only downside is that it will be deprecated.
