What do you mean when you say "not private"? Are you accusing the company of sending private data to their servers, as Google and Apple do? Freedom of computing on Librem 5 doesn't end with the root account. It also allows to natively run any desktop software and develop it in any language, without reliance on Google's decision on how one must use the phone, how your OS must evolve and when you may get your updates.…
Maintaining one's data as private requires that it is protected as a baseline. Privacy violations do not solely exist as telemetry or data offered up by the platform to some other party. The protection is achieved through security. The major goal of something like GrapheneOS is privacy, which needs solid security as a prerequisite. The blobs, while proprietary, are not opaque. They are able to be examined and they ar…
So you're conflating privacy with security, as I expected. These are separate matters, although I agree that privacy can't exist without security. And security can be achieved by different means, e.g., by choosing what to run. You can't force your threat model and security approach on everyone and claim that everybody who disagrees with you is insecure let alone has no privacy without good evidence.
> The security of a device should not be dependent on what you choose to run on it.
Why not? What's wrong with it? This is more or less how most desktops work.
> You should trust and be able to verify that the platform on which you are running the software prevents something malicious from accessing data which doesn't belong to it or otherwise violates the rules set by the platform (OS).
This is a big ask, and I doubt that many OSes can provide you such guarantee reliably. I would only trust Qubes OS with that, since it relies on strong, hardware-assisted virtualization and not purely on code correctness (my daily driver on desktop). I guess, regular CVEs confirm my opinion. On Qubes, the VM escape doesn't really happen.
> Thinking that you are secure because you only run "trusted" software on an insecure platform is cope.
This is exactly how security in a typical Linux server works, isn't? This is also similar to security through compartmentalization, when you isolate untrusted software from trusted environments.
I would even go as far as suggesting you to follow my approach at least partially, since installing and using any untrusted app on you GrapheneOS can destroy your privacy as long as the app has the internet access and can send tracking information about you to anyone.
