The problem with leaving all this data around is eventually the proletariat will begin prefering to share it all with each other. When they start doing that, they will begin to co-ordinate instead of compete. For awhile the information advantage will be with people who have money, but that can change.

Then they begin realizing things like Uber is owned by the Saudi Oil Fund and all the soulless corporations are really vampires owned by foreigners who only care to garden in their backyard but sh!t in yours...

I have a very optimistic viewpoint of this discovery; right now law enforcement uses it for an information advantage, but, that won't last forever.
