Of course they do. Traffic analysis is always a problem. They obviously know the src&#x2F;dst addresses and the package dimensions (including weight), as those features are necessary for the the delivery.<p>They still don&#x27;t know what&#x27;s inside the package. I really don&#x27;t see why this boundary is hard to understand. With snail-mail (fedex, usps, etc) there are even laws that protect the boundary between the envelope and the private contents. Why would you think software would be different?
