Why Linux Phones are Interesting AF

Rob goes through a list of free, open source replacements of Google or iOS on a Cellphone.

" Linux Phones are cool AF (as zuck)! Let me tell you why I think this. I'm going to get a Librem 5 delivered soon (hopefully) and I'm excited about what I can do with it. I even started writing programs for it before I even see it (see a short demo of what I've made for it). Why can I do this? Because it's Linux!"
