Consider the UK is right now [0], as we speak, passing a bill that forces an ISP to hand over browsing data, without a warrant, to non-law enforcement agencies (a list of which is in the source below). Agencies like the DWP (who handle unemployment, and have been subject to much criticism on how they make decisions and handle clients) will have warrantless access to browsing data for specific people.

A little far fetched, but if you're employed by one of those agencies, your boss (or bosses boss etc) can access _your_ data, find out how often you're googling basic information and use that information against you.
