It seems the system co-opts everything, including rejection of the system.
The mechanisms by which The One appears are rather simple and arranged in the Prime Program process: when the anomalies in the Matrix reach a certain threshold and begin to pose serious problems, a random human is selected by the machines to be born with a special code (the Integral Anomaly) that, as said before, ties and attaches all of the anomalies within the Matrix to the programming of this human. The Oracle, who is aware of The One's existence and purpose because it is her duty to guide humanity to find The One, will enlighten him to his true nature and lead him towards the Source where he fulfills his purpose of reinserting the Prime Program and resetting the Matrix. She does this by predicting the return of The One to the people of Zion to aid them in freeing humanity from the Machines' grip. The Architect, as creator of the Matrix, is also well aware of The One's existence and purpose, referring to The One as an "eventuality".
Grunge is a good example but the same thing happened to punk a generation earlier. Consciousness-raising sessions and second wave feminism quickly became unilever marketing cosmetic products using the language of empowerment. Pride was originally the first anniversary of a riot but now JP Morgan and the cops themselves are comfortable putting out a rainbow float. etc etc etc there are thousands of examples.
Anything that's visually recognizable as transgression will be commoditized until it's no longer transgressive. Many many cultural and art phenomena are downstream of and in response to this mechanic of consumer capitalism.
(I can see the other point of view, which is that Westwood was a nobody until consumerism took her and her designs to its bosom).
I guess I never really thought that commodification also worked for the values I grew into.
