For anyone with a logical mind this story tells us one of two things-

1) The ability of the government surveillance apparatus is not what they tell us it is. If there were an actual Carnivore style capability to scoop up and analyze data and communications systems, we would have long ago discovered who "anonymous White House insider" was. That this is their second book proves that such a capability does not exist. The writing style could have been analyzed in order to identify the creator and the internal emails and other types of communications with the publisher would long ago have uncovered the author.

2) Everything mentioned in point 1 is true, but this is a deliberate disinformation campaign run by the White House and authorized by Trump for reasons not yet clear. Therefore whatever is in the 2 books is not true.
