Antonym of manufacturing
Solution 1:
How about Dismantling Consent? "Dismantling" -- incidentally the last definition given by Gnawme for "deconstruct" -- seems to convey a careful taking apart of components that suggests the opposite of the careful putting together of components that "manufacturing" suggests.
Solution 2:
The title "Deconstructing Consent" may capture what you're after.
deconstruct, v. : to break down into constituent parts; dissect; dismantle.
Solution 3:
Dismantling works only if the endpoint of your effort is to see the components of the manufactured consent laid out for view. If, on the other hand, your aim is to undermine fraudulently manufactured consent and foment widespread dissent, then Demolishing Consent would better capture your purpose.
