I thought hang on, why don't I know about this potentially very interesting security conference?

I just got tricked into providing my data to "download" an ebook, which, on closer inspection, you can only "read" in a browser but not, you know, actually download.

The screenshot shows a) the email where it says "Download" and b) the missing "download" link in the upper left, which was removed by the uploader or hoster.

Just in case you want to know what it was, it's "The Hitchhiker's Guide to PCB Design" from Cadence. Never again.
