Pakistanis are addicted to 'conspiracy' theories and he who can garner most attention in this circle will ultimately get most media limelight within Pakistan and hence most money.
Pakistan is a simpleton Country and Society in many respects and it is quiet easy to herd the masses and profit out of it. And with certain Countries always looking to drag Pakistan's name and reputation into mud, these people's outlandish claims will go unchallenged and will be etched into global media's output.
This is not to say there aren't any problems with Pakistan -- there are some very serious problems and media and authors and journalists do a great job highlighting them. But unfortunately, certain class of 'elite' Pakistanis tend to view themselves as universe revolving around them.
And icing on cake is that these are same Pakistanis who typically hold dual nationalities and foreign visas and on slightest signs of trouble, quickly take next flight out of Pakistan in order to evade authorities in Pakistan. They from outside of Pakistan, they continue to preach against Pakistan.
