If by &quot;you&quot;, you mean aggregated data <i>about</i> you in lieu of cash payment.<p>Google&#x2F;Facebook&#x2F;etc are not selling <i>your</i> data, they are not selling <i>you</i>, they are selling <i>access</i> to you via advertisers, more specifically, they are selling <i>access</i> to people who like certain things and who live in certain areas who have certain demographic profiles.<p>If you&#x27;re curious about this, go sign up for an Adwords account and see how the targeting works - what you see there is the limit of what any advertiser using Google sees about its users. Facebook is much the same.<p>Get it right. Any ad-backed company of note does not &quot;sell your data&quot; and characterizing it as such is so divorced from reality as to be a blatant, willful lie.
