I doubt it would be that simple. I'm sure it would take a lot of effort to alter the memories of every person in Totto Land. At the Sweets Factory at Cacao Island, Pudding had the WCI 31 chefs enter the factory one at a time when altering their memories. So it could mean that Pudding's abilities have limits and she may not be able to alter the memories of so many people at once.

Edit: Besides, I doubt Big Mom would just ignore what the newspaper said. She'll be a simpleton to not wonder about the discrepancies in her memories and get to the bottom of this.
