Since most of us aren’t looking at websites via a Tor connection, we’re leaving digital footprints all over the place. The sites you visit may have a surprising amount of information on you, even if you’re not logged in, and even if you went to that site inadvertently. That’s why the Justice Department is trying to compel a web-hosting company to turn over everything it knows about anyone who ever clicked on a site that is critical of President Trump. It’s also why that company is fighting against this demand.

The company hosting the site, DreamHost, explained in a blog post what was going on.
