Now understand, thank you.
Before your kind explanation, I indeed did not fully grasp what Purism was doing. I was naively thinking they were doing a privacy-focused device that I could someday use everyday.
But instead they are doing a device that will run Linux and will occasionally make calls. I had one of those: Openmoko. Still have it in a drawer.
Without making a device that is actually useful, which will survive more than one iteration, those are futile attempts. Truth is: one small company will not be able to make a full well-integrated phone software in the time/money the company is allowed to burn. Unless they embrace "outsourcing" apps to existing ultra-portable (web) ecosystem, the attempt is doomed to fail.
Sadly, but if the course continues, I will make my prediction: Purism will successfully release Librem 5, there will be a half-baked UI (like MER/Openmoko/Sailfish/OE), half-baked bunch of native "Notepad" apps, no one will seriously use it, and it will be the last phone Purism will release.
Then, the circle of life: a new company will try the same.
