License plate readers, used by both LEO as well as third parties wanting to sell the data, often cruise parking lots where events are happening, such as concerts, ball games, and the like.

Some towns where the main route takes you through it, also have set up such readers, capturing the flow of the traffic.
Internet places offering services such as Ancestry and others, often co-operate with the law without a warrant, on request to see if some family member of the same DNA tree might be in their data base when trying to identify who might be a person of interest or a suspect at large, yet unknown.
Companies offering free VPN service get to see your browsing habits and that data is for sale. You want better security you have to pay for it and not all of them honor their billing. All those apps you load on your phone, if they are asking for access to data on your phone that is not required for their service, they are gathering data for sale so be especially leery of freebees, how you pay for the service, isn't money up front.
