That doesn't make any sense for me. Pixel devices, especially generations 8 and 9, are excellent devices for GrapheneOS. They support MTE and have 7 years of full security updates since the launch day. They are very secure Android devices, and we hope that the Pixel 10 will meet the requirements of the GrapheneOS project.
GrapheneOS is working with an OEM to release mobile devices that are natively compatible with GrapheneOS, which is great, but for now, it's not available at all. If all goes well, we hope for 2026-2027, but if you want GrapheneOS now, don't count on devices that don't exist yet and just get a Pixel 8 or 9. Buy used if you don't want to give money to Google, although that makes no sense to me. A common misconception is that GrapheneOS is anti-Google, which is not true. Its goal is to provide a secure and private operating system; ideology has nothing to do with it.
