Every single one was written with Trump's active assistance using his own words.
If anything, speaking with them before hand makes it easier for him to call them out on their misreporting.
I'm not aware of a single one that proved Trump misquoted himself. He set himself up and put his foot in it.
There may also be some other benefit Trump gleans from personally interacting with them.

If you’re good at reading people you may learn a lot from your enemy that he/she never intended to reveal.
Other than make him look bad what did Trump reveal in any of these cases?
“Every single one was written with Trump’s active assistance using his own words.”
Right. And if he hadn’t actively assisted, they would have still been written and they still would have been hit pieces that but would have been even more reliant on “anonymous sources”, rumor and innuendo.

Let me give you some examples. When having these types of interviews there is usually preliminary talk, greetings, etc. before the direct questioning commences. During this kind of small talk, you can often learn some things the person never intended to reveal. A simple question like “How’s so-and-so doing?” may lead to a response that reveals something the person never intended to reveal. The mood of the enemy can also be useful information. Are they cocky? Do they look worried? Do they look to be acting independently or are they doing someone else’s bidding? Useful information to someone who knows what they’re looking for.
