The CTA as secret agents of Shugden? My immediate automatic response would have been "No,impossible! How can one reconcile the 'vile' acts of CTA against Shugden practitioners with the possibility that they are are on the same side of the camp of the victims of their cruel heartless anti-Shugden actions and measures? "
But then, what about the shocking almost incredible revelation made by Samdhong Rinpoche when he was on the verge of retiring as Kalon Tripa, head of the CTA? He had said that what he had done all along(acting in concert with the Dalai Lama in enforcing the ban on Shugden practitioners ) had been done out of Guru Devotion: he was merely following the instructions of his Root Guru, Trijang Rinpoche! As Beggar and others have pointed out, the older generation who are members of the CTA are mostly students of great masters like Pabongka Rinpoche, Trijang Rinpoche and Zong Rinpoche. If great current Lamas, who were students of these great Masters, have steadfastly stuck to their practice of Shugden given to them by these great Masters who were their Root Gurus, I cannot see how and why, older members of the CTA, who also are students of these great Masters would have dared to break their samaya with their Root Gurus by stopping their Shugden practice. It is more logical to see them going underground with their Shugden practice.
Thus the hypothesis that they are secret Shugden practitioners and agents does hold water indeed. And when the ban is lifted we'll have them coming out in full force in the open to declare themselves as Shugden practitioners! Pray that day will come soon with the lifting of the ban! Furthermore, if this hypothesis proves correct, then this lends greater credence to the other hypothesis that all this is a part of a big plan masterminded by great Masters like Kyabje Trijang Rinpoche to ensure the rapid spread of the practice of Dorje Shugden especially in places like populous China, the great powerhouse of today.
