I don't understand. The "expert" that said that it's a 'dead trap' is just a Reddit user? Does s/he have any credentials that make the newspaper repeat it?
Haha wow
Where is the word "expert" used?
Are those citation quotes you're using around "experts" or scare quotes? The article literally says that the tunnel has been called a death trap by someone on Reddit. The word 'expert' does not appear in the text. What you're fuming about exists only in your imagination. Or, as they like to say among cryptofolks, "stop the FUD, do your research".
