It's not censorship they just want to make sure they announce it before it appears online from another source. They ensure this will happen and basically confirm its imminent announcement by promptly removing any threads that crop up about it.
It's clever stuff that's way beyond our limited capacity for understanding what is happening and it's ultimately for our own good I'm sure.
Working on the premise that Cake=Bakers, which incidentally always cracks me up, it's very important for a Baker not to open the oven door too early so as the Cake doesn't collapse in the middle due to it not being baked properly throughout.
So although we can all smell the goodness wafting from the oven already we have to be patient because it's not ready to be taken out yet and even then it will need to be placed on a wire rack and allowed to cool first.
