My understanding is they want off-the-record information from unnamed sources. These aren't public questions like at a press conference. Those can still occur under the current rules.
If they publish off-the-record information without approval of authorities, they will no longer be accredited to attend press conferences. Of course no self-respecting reporter is going to accept this - if you do, next step is "if you publish lies about our president, you will not be accredited" - trust me, I know, this is how it starts.
