So the Linux kernel may support the Librem 5 for life, but what’s even the point of all that effort if the phone is just going to irrevocably die on you after a couple of years?
You may want to keep that in mind before you buy one. I ordered a Librem 5 last year but got aware of the issue only recently.
Except if Purism opens a store in Europe. And they intend to (not that there is a big progress currently).
