Smartphones are not safe

> Titan M, maximally open to the public That is absolutely FALSE. The firmware binaries in Pixels (Titan M included) do not correspond to published sources. Although, Google uses (and contributes to) open titan repositories, the final product used in Pixels is proprietary. You can’t build Pixel’s Titan firmware from Open Titan sources the same way you can’t build Google Chrome from Chromium sources. Both Titan and Chrome are black boxes. Since the rest of your post is based on this false premise, there is no need to respond further.
