There's a string you can type in blind that bypasses HSTS. Works on Chromium browsers. I don't want to make to too easy to find so I won't say it here but you can look for it.
I also find it goes against the ethos of HN to try to prevent a user from controlling their own hardware... if I want to MITM myself, I should be able to.
Saw that a few days ago but I don't do Chromium browsers. Cest la vie.
Appreciate the attempt.
