Interesting. I didn't know much about it other than having heard the name until I just looked it up. The idea of physical kill switches is pretty cool. My only question is, given that the OS isn't based on Android, does it basically not have any apps? The website mentions that it sort of turns HTML 5 apps in to some sort of native-like app by downloading it and sandboxing it. Is that the only sort of apps that are available for it? Or do you install full Linux applications on it? The website doesn't make it super clear.
My (limited) understanding is: the Librem phone has a very limited number of apps.
The vendor tackles existing GTK (?) apps and tries to make them work with touch. But it seems to do so on a best-effort basis so nothing is guaranteed.
I acknowledge that Purism is a small company and that it can only do so much. In case it fails, my gamble is that enough people are going to contribute and keep the most important apps working.
