> Based on stories I've heard from people work in industry, every major ISP in the UK keeps DNS query logs and "internet connection records" and makes these available to authorities (without a warrant)

there's no "story". it's the law in many countries:

> In many countries, ISPs are legally required to monitor and store data about your browsing history for an extended period of time. This is called mandatory data retention. This data is used for policing, government surveillance, and sometimes even advertising.

> The length of time that ISPs must retain data varies by country. The U.S. government requires ISPs to keep records of customers’ internet history for a minimum of 90 days, while the UK and European Union requires ISPs to keep browsing records for up to 12 months.
