Pixel has some great features and is an interesting deGoogled OS but their approach to security is just silly. It’s basically “we will not let anyone compromise on security because it could be bad PR for us”. They pretend they care about the brand but then they simply wont let majority of users use their OS. I think normal team would simply make Graphene OS available for other phones and then have some Graphene OS Extended Security version compatible only with select phones. Their purist approach only turns away potential users.
