You're right. At the moment it's difficult to download Tails anonymously, especially with everything we know about XKeyscore targetting.

It's a problem that others can help fix by setting up mirrors on HTTPS. Ditto with hosting the website on a Tor hidden service.

The main ISO link is able to be used via HTTPS (by adding an "s" to the URL) but it's got some compliance issue. HTTPS would likely not provide anonymity, since it leaks to much metadata; might be wrong, just my opinion.

If you use a distinct server for Tails then you could still spot the downloads, you'd need HTTPS and serving from a busy mirror that serves a lot of other apps and systems as well
