You are already paying for it with massive crawling of your personal information.

Are there any events over the last decade that leads to believe either of these are true?

1/ if you're paying with money, you won't have to pay with personal information

2/ if you're paying with personal information, you wont later have to pay some other way as well

Monopolies (or near monopolies) like to double-dip. A good example of this is net-neutrality. You already pay to be a customer of your ISP, and for your ISP to provide you with Internet access. Your ISP stands to profit even more if they can charge the rest of the Internet for supplying that access to you.

Forget monopolies - the New York Times is a double dipper along with the long standing practice of selling mailing lists when a company goes bankrupt.
