Librem5 has iPhone class pricing. It's no alternative to FirefoxOS. I earn decently, have mid-range need for security, and I won't buy iPhone nor Librem5.
You can already run Purism on other machines(laptops, desktops, etc). The mobile version will essentially be Purism with gnome-mobile UI. I’m sorry to read that you don’t think an open device that will have its drivers available and probably work with Android, isnt worth the cost.
