The link works fine without Facebook account on Tor:
It didn't work for me, despite a circuit change. A third circuit change just now and it did work. Guess I was just unlucky. Thanks for sharing the image anyway!
I find the whole thing very disingenuous if I'm honest. "You're safe and sound when you do so, as you need your Ledger Nano S/X to confirm the transaction." I mean, technically that's correct, but as you as you confirm the transaction you are no longer safe and sound in any way since your coins are no longer protected by your hardware wallet, are no longer in your control, are in the possession of a third party (and not even Ledger themselves), and you have no idea how good their security is. All that information seems to be inexplicably missing from all the explanations they are giving as to how this works. It's
almost like they don't want people to realize they are losing all security and privacy by using this.
