To be completely honest, Android should be considered as "insecure" for the same reasons. It's binary blobs that are hacked around by distributors with limited support after a year or so (when phones stop being manufactured and widely sold). Can we just get a proper Linux OS running on mobile devices already that's properly open source and easily re-flash-able? It's clear that ARM is here to stay and if Linux is to stay relevant, it needs to move towards support for one of the most popular computing devices on the planet. Desktops made their way into each home and mobile have made their may into each pocket. That way, running something like Signal would be more trust-able coming from a package manager, especially with something like Debian's reproducible builds.
