I use GrapheneOS, and wouldn't have it any other way, but its prolonged existence depends on Google not making any asshole moves in their next Pixels, and on the (highly appreciated) efforts of a few dedicated individuals.

And like Linux on the desktop: it offers a better experience for everyone who either has the knowledge to step off the beaten path, or has someone who supports them. But that is just a few percent of people. The rest gets what market forces dictate.
