Doesn’t GrapheneOS have a lot of benefits besides the 3 pixel-requiring hardening features which are removed in Graphite (and the 3 others which are disabled by default but can be re-enabled on some devices)?
I’m not disputing that those hardening features are worthwhile! Pixels with Graphene are obviously much more difficult to exploit than phones without those features.
But there are billions of non-Pixel phones in the world which aren’t about to be thrown away, and the vast majority of phone users absolutely cannot afford a Pixel. GraphiteOS (if it actually works?) seems to me like it is probably a major improvement over the other options available for them.
It breaks the security model. Graphene doesn’t only support Pixel for fun. Pixels have the best security hardware features, unfortunately (until the Motorola device comes out).
I would never use this ROM, personally. At that point I’d just use something like Lineage.
My impression is that Graphene-without-the-features-requiring-Pixel-hardware would still be a much more secure operating system than Lineage (or the other options available).
It ultimately depends on your threat model, but many of the most important security features in Graphene are at the hardware level. Without those, it’s very possible that a bad actor could bypass the rest of the protections, since Graphene is designed with those hardware features in mind.
I saw it already, but those hardware security features also secure the features you mention there. The other features were developed with the hardware security features in mind. Again, without secure hardware, it’s possible for your software to be modified and no longer secure. That’s the broken security model I keep mentioning.
While it could definitely be more secure than other ROMs, security was never tested without the hardware features and thus it could also expose you to attacks because of that. Worse, it could make you assume that you’re secure when you’re really not.
An excellent example is Cerberos. GrapheneOS is able to completely block attacks from Cerberos by disabling the USB port data lanes entirely, something that most (if not all non Pixel phones) are unable to do. Cerberos uses many zero day vectors to break in though the data lanes, and in this case you likely would not be able to block the attack. They’d be able to dump your phone contents and then much of the software security features wouldn’t matter.
Should the world just throw away the billions of non-Pixel devices in use today?
And/or should everyone just give up on improving security at all for the vast majority of phone users who cannot afford Pixels, since they can’t ever be as secure as a Pixel?

Why are you acting like GrapheneOS is the only custom ROM available? There are other GSIs and ROMs that non-Pixel users can use to keep their older phones going.
I didn’t say that they should be thrown away? I’m not sure where that came from.
I said that I would rather use something else that was designed without the hardware security features in mind. It’s all about your personal threat model, and mine does not align with this fork of Graphene. I’m either going to use something like Lineage which has at least been tested from a security standpoint (and does not have possible zero days because of patch working a ROM designed with specific hardware features not available on my device) or I’m going to get a used pixel and run Graphene. Even Calyx would be preferred to this once they start up development again.
I think the reason GrapheneOS never did a GSI is because most of their security improvements rely on specific hardware calls that GSI abstractions don’t provide access to. This probably would still be an improvement over lineage though, just not as secure as base Graphene is.
the containerization features alone would make graphene worthwhile over other roms. i hear graphene can pass play integrity attestation inside those too.
It depends. I run GrapheneOS and it can pass everything except the most strict integrity check (which is just that you’re using a custom ROM at all).
In practice most apps don’t have any problems. Google assistant doesn’t really work for me but I’ve seen posts saying people have gotten it working. Google wallet and Google Pay are also explicitly blocked by google, so they will never work.
The developer of GrapheneOS is… Interesting, to say the least. Restricts the ROM to a select group of devices, and is very toxic to people who disagree with or even question him.
I understand him though, GrapheneOS without the underlying security hardware is a huge security risk for the end user. It makes people think they get benefits from running a secure os while in fact, they are at the same level as running lineage.
That’s vastly underestimating the hardware on other devices as well as overestimating the danger. There are plenty of software optimizations that can be done to enhance security that work even if the hardware isn’t ideal. Simply ignoring those devices is letting perfect be the enemy of better. Not everyone wants or even can buy a pixel, and that just excludes all of those users (and also sends even more money Google’s way, which I would honestly like to avoid).
There is a lot of people arguing about fine distinctions ITT.
The GrapheneOS leadership (well Daniel) are uncompromising for a reason: this fork will be fundamentally less secure.
You are also right: there are useful features that will improve security on GSI devices. As always choose your threat model.
Hopefully both parties can play nicely.

But why?
so that many non-pixel devices can have an OS with most of the benefits of GrapheneOS?
But those benefits rely on the Pixel’s hardware. This is contradictory.

What’s with the hostility?

Wait… an improvement over Lineage ? That alone makes it worth existing in the first place.
At first I thought, Graphene OS without it’s features… Why? But what you say sounds like it actually makes sense.
