@luana@wetdry.world It will fully support using other operating systems including users making their own builds of GrapheneOS. It's part of our hardware requirements. We'll likely be able to make hardened builds of firmware and drivers which can be released in an official way for easy builds without needing to extract anything from the GrapheneOS or Motorola OS factory images.
One of the largest complaints of Pixels I’ve seen is that they’re too expensive. These will cost twice as much.
