When you use an
https:// link to point to a webpage, image, spreadsheet, dataset, tweet, etc, you're identifying content by its location. The link is an identifier that points to a particular location on the web, which corresponds to a particular server, or set of servers, somewhere on the web. Whoever controls that location controls the content. That's how HTTP works. It's location-addressed. Even if a thousand people have downloaded copies of a file, meaning that the content exists in a thousand locations, HTTP points to a single location. This location-addressed approach forces us all to pretend that the data are in only one location. Whoever controls that location decides what content to return when people use that link. They also decide whether to return any content at all.
