The Streisand effect only works if you don't have the media in your pocket. The media was happy to carry water on the Hunter Biden laptop story until after the election, I suspect most people don't know about the diary and the FBI's response to it. They just won't cover it like they haven't covered a lot of things in the past few years.

I'm sure some exec at HBO makes the final call on what they actually publish, if Oliver has actually anything the most it probably results in is that exec being owed some favors down the line.
