It gets into the incredibly murky water of how the web works. You're just issuing a request and getting things back. Sometimes in a web browser, sometimes not. But the content itself may still be copyright. You can't just take it, even though for now, the publisher/server is allowing you to view it for free.
But what if you only chose to view some of the content (e.g. block ads). What if you apply your own styles to change the way that information is displayed? You're just changing the way the browser represents that data. You're not redistributing it as your own at this point. What if you store that data, but don't republish it; just used it in some each algorithms?
There are a whole lot of interesting grey areas here, but many that already have precedents that side more with the copyright holders.
