Questions for linux phone enthusiasts:
1. What's to stop Instagram etc creating apps for mobile linux? (In principle I mean, obviously there's no market yet)
2. Is it possible to set up phones with users, so (in principle) you could have a child as a user who can't install anything without the root password?
Thanks ahead of time (this is for my forthcoming blog post on the benefits of linux mobile for young people)
For the second part, you could with #mobian or #postmarketos for example, using phosh/phog as the DE.
You can create user accounts and at boot choose which one to login to.
I am not sure about other shells, but I suppose so.
