Except the theory doesn't state that Shepard is indoctrinated, but that the reapers are TRYING to indoctrinate him. There was nothing to notice by anyone, the Reapers have been trying since the first time he met them, but they never succeeded. The ME3 ending was their last ditch effort, overloading his mind trying to activate all the little bits of influence they'd managed to infiltrate so far.
