I'm a bit confused here, does copperhead still exist?
From what I gathered everyone moved on to graphene, including the original architect.
I've not seen anyone mention copperheadOS as a modern secure phone in a long time. Not trying to denigrate the post but it's somewhat strange to see them appear out of nowhere.
Also, on my barely secured, out of date firmware phone, the site doesn't work because I block js :/
Truly long for the day people at least attempt to make fallback no-js sites or at least text only static pages like some 90's ftp server for us weirdos who don't need nor want interactivity. Last I looked something like 80% of Android and 50% of apple phones were end of life and yet still used.
