Again, I don't believe it's accurate or honest to call this coercion. These files were obtained from a content delivery network by visiting a url in a browser. Nothing deceptive, cunning, crafty, or coercive about it. Let me ask you, what files am I allowed to access on a public network? Must I ask owners permission before visiting their websites? Must I be able to find it with a search engine? What constitutes a file which anyone is allowed to view?
This is incorrect. Actually, yes, the files were in fact browseable and Akamai servers typically front with DNS names that presumably resolve to their any-cast addresses where they use SNI to select content bucket, so there would have been a "friendly" name involved. Going to https://server.com/folder displayed a list of folders and files all hyper-linked and connected as is common on the internet. The fact that the server was initially discovered by way of a crawler, a scan, is irrelevant (this is actually how search engines discover content, btw). The fact that a browser could browse these files suggests that it is not "well beyond the realm of browsing public websites".
Exploration of public areas isn't illegal. There's no law mandating that viewing a website though the browser is legal, and any other means not. Techies legitimately access websites in all kinds of programmatic ways. Intel made their data publicly available. That it wasn't accidental doesn't change that.
There are often ways to beaches and other spaces unadvertised, but otherwise OK to use.
Sure looks to me like a potential landmine for people. Bad practice with big pockets should still just be bad practice with the same consequences for all who don't bother with better practices.
