I don't think Disney is really an adversary in this scenario (where an adversary is not purely economically transactional); the recognition is primarily geared towards (a) analyzing general patterns to optimize (b) selling you more things you would be interested in buying. Their motivation is entirely economical.
These detection tools aren't perfect, and there is a diminishing return on getting that last few percent of people who slip through the cracks. At some point, it isn't worth the effort.
China, on the other hand, is motivated by more than mere economics. It is also interested in analyzing general patterns- they are a partial-command society given the extensive centralized planning that goes into the economy and social behaviors. However, the people who attempt to go unseen are precisely the most important people to observe- the bad actors, the malcontents, those most likely to cause trouble (乱) to an otherwise harmonized society.
