What if the point of it all isn't to make the consumer money, but to make companies less indiscriminate about gathering and storing data?
Can't you achieve the same effect at user level by faking some data + messing with tracking via Firefox containers + Ghostery + Cookies AutoDelete?
The point of making the companies change is that most users aren’t computer literate enough to understand the problem, it’s consequences, or the mitigations. The knowledge asymmetry between the average user and the companies collecting and using this data could hardly be more vast, and that creates a situation where companies can effectively prey on less knowledgable users. If the wide majority of users aren’t capable of finding/using the available user-level solutions, the problems will remain rampant.
