Third party: &quot;You&#x27;re welcome! Since you seem to be very interested in that specific subject (the destination IP address happens to map to a site specified for that subject), we sold this information to Google and they will now show more ads regarding that subject.&quot;<p>No, seriously. I believe it is good practice to encrypt all data over all kind of wires (public or not). However, most of the time, we do not encrypt metadata, which can be just about as useful as the actual data (and way easier to analyze). Do you really think that any government cares much about what you say to a specific person? They only care that you talk to that person, when you talked to that person, and how frequently you talked to that person. The same goes for almost anything. If your ISP were interested in your data, they would actually value metadata a lot more then the actual payload because metadata can be analyzed quite easily and reliably.<p>Tor was (and still is) your only protection against these kinds of attacks because your ISP only knows you&#x27;re talking to some Tor nodes, the Tor nodes can see very few of the websites you visit (or email recipients you send to) because you will use another nodes for the next website&#x2F;email, and the website will not know who you are if you don&#x27;t authenticate because many requests can come from that Tor node.
