Exactly this. There are many predictable comments in this thread about why they think mass adoption of Linux phones won't happen. I even agree with them, but they are missing what I think is the point. I don't care if they take over the world; I want a means by which those of us that do care about privacy and openness and control can opt out.
Note that small pool of people actually caring may be enough. See whoever buys Pinephone and Purism-Librem.
