It's nothing wrong with a user deciding "I realize something is wrong, and I shouldn't trust that anything on this website is legitimate, and I shouldn't give it any information, but I'd still like to read the story/article/blog."
There should be a low-opacity button inside the "Advanced" menu.
But if the button isn't there, that's probably because w3 has HSTS enabled (for past visitors), which tells the browser to never load unencrypted. The `thisisunsafe` workaround is there to be a middle ground between actually making it impossible to load and preventing users loading an unsecure page when they shouldn't.
I think a reasonable compromise would be a button that pulls up a dialog prompting you to type out a consent message. The dialog tells you what to write instead of keeping this as esoteric knowledge, but the user is still compelled to at least read the warning instead of blindly pressing buttons.
This is the sort of thing, if you're not in the know than you probably dont understand the consequences.
Understanding the premise and importance of HTTPS and knowing about some esoteric hidden UX of some Google software are not at all the same thing.
(For them, undo is a much better replacement. Even gmail's 'fake' undo for unsending email.)
Engineers can be so out of touch sometimes.
