Bouncing on Smalahove's comment above suggesting that Glen finds someone with high moral integrity within the organisation, I start suspecting the opposite. I have the impression that someone there seems to hold a personal grudge against Glen. This sudden 180 deg reversal in their attitude, the relentlessness with the contracts rewrites and obsessive efforts to dismantle APTA after endorsing it in the first place almost has vengeance written all over it. And that's weird because the overwhelming consensus here is that Glen is not the kind of person that has untold numbers of enemies.
So what is it that's driving all this? Do we/does Glen know everything? Who stands to benefit from the dismantling of APTA? Maybe that's an angle to consider
