Personalized ads have to know about you in order to target to you. You'd assume the more they know, the "better" they will be at targeting. This leads to an industry-wide race to collect as much data about people as possible. This leads to a lot of large, valuable, aggregated datasets stored in a few large central locations. These datasets create strong incentives for criminals to steal them and governments to abuse them. I don't want any of these things. I don't want to be known to various sketchy entities. I don't want to be abused. Is all this stuff really worth it to you just so you see some better ads? I don't even want to see any ads. I simply don't want advertisements to be interlaced throughout my life. And I damn sure don't want them to be watching me back.
