"A cheap surprise at the expense of player choice?":

There is no player choice, it's just an illusion. Claiming this series has actual choices that impact things majorly is just outright denial.

Indoctrination was important to the story, considering Sovereign would've gotten nowhere in his plans without it. Also TIM wouldn't have been a bad guy nor would he be an advocate for Control. We wouldn't have it foreshadowed in the beginning of 1, we wouldn't have a DLC that explains where Indoctrination comes from, and it most certainly wouldn't give an idea of the extent of it's abilities.

So many more examples...
