Access for Superadmins to information in private task (ex: collaborators)

Some time ago, a colleague of mine needed access to a private task. I asked Asana support to add me as a superadmin to this private task. They refused, citing the fact that the task is active and there are followers there. Here it’s ok, but when I asked for information about the list of the task’s followers, they also refused to give it to me.

Why can’t the superadmin be told the list of the private task’s follower list? Does this violate privacy in any way?
