AlphaElwedritsch As you very well know, other devices do not even come close to meeting the project's criteria, they're simply not an option. It's not even like we could compromise a little bit to meet them halfway. The difference is enormous. Our security requirements are already lower than what current day Pixels provide to allow room for another potential device, but even with those, nothing else comes close, or if it does, doesn't extend that to be usable by 3rd party OSes.
The expectation is always that people will have to buy a device to run GrapheneOS, as the project's goal is having robust and secure devices that we work on (especially considering some features are hardware-dependent), rather than broad device support of horrible secured devices.
As far as we know, Google will continue releasing a series devices which are cheaper than the flagships while hopefully still meeting the proper security requirements.
Supporting a "budget" device that doesn't even begin to meet the requirements we need to be able to provide security and privacy will not happen. We would essentially be lying to our users by telling them that what they're getting is GrapheneOS, because it would be such a huge difference.
