I wonder why none of the previous Ones have not informed the founders of new Zion that there had been another Zion previously and that Matrix still have them.
I think that such knowledge may be of crucial value for the resistance. I know it may be devastating for their morale, but hiding the information also may be seen as an act of treason as it is basically handing the newly found enclave to the enemy.
[EDIT]
According to answers to Is the last "One" present at the re-founding of Zion?, The One has a possibility to inform them as he meets them in person.
[EDIT2]
I know The One is given no choice but to accept the offer to reestablish Zion as the current Zion is to be wiped out and he is unable to prevent it.
What I am asking is why is he complying to his role as real-world agent of The Matrix? Why is he loyal to it instead trying to defect in any way?
