I do sort of believe that there is a lack of freedom in how phones are developed as compared to computers in how hard it is to say run pure linux on most phones (if not down-right impossible on most)
I know people say that Linux adoption on Computers is low, but to be honest, Installing Linux itself is one of the most straight forward parts without much lock-in atleast on most computers I use (Except the mac ecosystem like macbooks where I feel like some work is being done too but that feels a bit complicated to me)
One of the benefits of Linux is that you expose yourself to open source philosophy and then you see it everywhere and you seek it everywhere. I remember just learning about alternativeto and then finding all open source alternatives of things too. It feels nice to know about open source and searching it.
A lot of these is connected in a way and I hope that ethical computing initiative helps some people chose their devices in such manner.
