The goals are completely different, and the actual implementations are miles apart. They aren't comparable apart from a common AOSP ancestor.

Open source or source availability is not a requirement for auditing a system. There would be evidence that would have almost certainly been found by now if this was the case. It is up to you, or the claimant, to prove their claims. I can say that there has not been any evidence of data collection by hardware components found, despite years of Pixel devices being tested by security researchers and mobile forensics companies. Not only that, the actual technical capabilities of the hardware (isolated component without networking capabilities) backs that up.

What do you have except fearmongering?

GrapheneOS (like any other AOSP fork) is technically a Linux based OS. They run a modified version of the Linux Kernel. What matters is the changes they have made to the kernel, as well as enforcing AVB, SELinux, etc. etc.

"Linux" phones that run modified desktop Linux distros are hugely insecure devices that lack many basic security and hardening features.

It's not a matter of being paranoid and the GrapheneOS project members are not paranoid. It is simply a matter of Murena/eOS/Gael Duval making claims about their products that are misleading, false, and harmful to users.

CalyxOS is not hardened in any way and is in some ways less secure than stock AOSP. They are also on a hiatus and have discontinued updates: https://discuss.grapheneos.org/d/24791-departure-of-calyx-calyxos-leadership-and-discontinuation-of-calyxos-updates

There is no "hole". It has nothing to do specifically with being from Google, only that no one else but Google is manufacturing devices that meet the hardware requirements and have full support for alternate OSes.

It is an isolated component without networking. This is not evidence that unknown data collection is occurring. You need to provide actual evidence that it is.

He lied about stopping use of GrapheneOS. He can be seen in videos long after still using GrapheneOS on his Pixel. Also, the reasons he stated for not using/trusting it were nonsense. There was not, and is not, a technical way to target a user with malicious OTA updates.

He was also one of 3 owners of a for-profit telecom that included Nick Merrill (Founder of Calyx). https://sec.gov/Archives/edgar/data/2009536/000200953624000001/xslFormDX01/primary_doc.xml is the SEC filing for shares issued in February 2024 .

This is definitely not true. GrapheneOS is focused on privacy, security, and usability. It has many features that are solely for increasing privacy and control and implemented in very robust ways. For a couple of examples, see the Contacts and Storage Scopes features.

This is a common misconception people has as a result of misinformation being spread.

They have officially stated that they can support the 10 now, but it will have to wait until after the port to QPR1. https://xcancel.com/GrapheneOS/status/1960792610114511190#m

That device didn't meet the requirements for GrapheneOS even when it was supported by the OEM. As of now, it is an EOL device and is highly insecure. https://grapheneos.org/faq#future-devices

LineageOS also significantly regresses security compared to barebones AOSP.

• Userdebug builds
• No locked bootloader or verified boot
• Incomplete backports of patches
