Author of Three Cups of Tea, fabricated his memoir?

Read this on themalaysianinsider.com, and started googling. These are what I found:
1) The author's charity organization has taken credit for schools in Afghanistan and Pakistan that don't exist.
2) The porters who accompanied him say he was never lost, and went back to the village a year after his first trip.
3) Mortenson also claims to have been kidnapped by the Taliban, but all the men in a photo from the supposed kidnapping are not actually Taliban, and say they never harmed Mortenson.
4) One of the men, according to CBS, is the director of an influential think tank whose scholarly essays have been published in the U.S.

Mortenson's side of the story: 'I stand by the information conveyed in my book, and by the value of CAI's work in empowering local communities to build and operate schools that have educated more than 60,000 students.'

Mortenson said the account of his experiences in Korphe 'was a compressed version of events' that took place in 1993 and that local people's different concept of time could explain the misunderstanding.

Mortenson insisted that he was held against his will in Waziristan in 1996, though shifting tribal loyalties may explain the conflicting version of events.

He also maintained that the fraud allegations were fabricated by a disgruntled former manager, and that some of the money raised by CAI had been used to build an endowment rather than channeled directly into school construction.

'I hope these allegations and attacks, the people doing these things, know this could be devastating for tens of thousands of girls, for the sake of Nielsen ratings and Emmys,' Mortenson said. (Got this here)

Who's telling the truth? Does the truth matter if his story has inspired many to contribute to the society?
