The Times article highlighted the need to be seen as relatable and authentic and I think that this InstaAngst (have I coined a new word?!) is a fairly conscious attempt to be seen as "one of us", a mere mortal, in the hopes we won't notice their businesses expanding. The one thing they make clear is that it is their space, it is not a place to hold a conversation, to have a (constructive) disagreement - fangirl only. Such a shame and, ultimately, I think it will do them no favours as followers become more and more savvy to their techniques.
