There really needs to be a third way … how are Linux smart phones looking? No hope of getting WhatsApp etc presumably but at the very least a fairly solid browser should be possible …
The other caveat being that there are still many apps that are not designed for mobile form factor, and while there is strong work on libhandy and many apps use it for responsive GTK apps, there are many great apps were work hasn’t yet started for mobile sizing/touch input/virtual keyboard
What’s the best way to get involved?
Also submitting issues and spreading the word help. Mastodon is where many of the developers in open source world hang out so follow @linmob@fosstodon and Librem folks and you’ll find the community.
Testing, sponsoring, buying the hardware all great options too.
