> In terms of exploitation, I think there's definitely an argument for users paying to, for example, not be advertised to or have their data withheld from marketing exchanges, however there's no demand for it. Where do you get the idea that there is no demand for this ? It's a recurrent demand and it is consistently declined for business model reason by the facebook-like (see investor storytime[1]). Then there is a compelling argument that paying not to be advertised is only going to make you a more valuable target to be advertised to.[2] Likely paying for having your data withheld from marketing exchanges will increase the price of your data on the market while not providing you any way to be sure it has effectively been withheld. The only way is for this data not to be collected in the first place.
