I did not know what 're-targeting is'. So found a definition ".. Unlike typical banner ads, retargeting ads are a form of online targeting advertising and are served to people who have already visited your website or are a contact in your database (like a lead or customer). .." [1] My general feeling is that technology needed for modern advertisement industry, and for law-enforcement/government/political online surveillance -- is almost identical. No wonder, that companies specialized in technology to enable audience-specific ads, and 're-targeting' -- are the same companies that are looked for to supply/integrate surveillance technology. I am even now connecting the dots with advancements of Image recognitions, deep neural nets, -- with the drive for better surveillance technology, under the cover of targeted advertisement (as face recognition benefits both). I am also no wondering if much of much opposition/road-blocks to people using VPN (eg Google.com constantly asked me to choose bunch of pictures before I can use it, with VPN) --- is the negative commercial impact that VPN usage has, on targeted advertisement, and surveillance.
