The thing is, you most probably gave away your data to the big companies for free already.
Facebook, Google, Amazon ...
These companies will not rebuild their product to implement the coin of an outside company to allow them to make money with the data they already got for free.
So new merchants or new community companies might include it but the ones that can use your data for free will keep doing so (or develop their own coins, as FB is said to do if you believe the rumors.
And the system will only be build, so till now nobody even knows how and if it will work.
You pay for an idea for now, which is fine if you think it will work out in the long term.
