Hmm... that looks like a pretty skewed comparison. It's as if somebody took the security features that make Graphene stand apart and compared everything else to them.

No contention that Graphene is safe, but categorizing other OSes as "pretty bad when it comes to security" because they don't copy Graphene is a bit of a stretch.

Eylenburg's site is focused on privacy and security for the comparisons. GrapheneOS is the only privacy and security hardened OS included in the Android-based OS comparison. None of the other operating systems listed in that comparison keep up with Android privacy/security patches or provide significant OS level privacy or security improvements. Many GrapheneOS features aren't listed by the table or are grouped in huge generic categories such as "Hardened system components". An example of a major privacy feature not listed by the table is closing the leaks in Android's standard VPN lockdown mode. GrapheneOS fixes all 5 of the known outbound leaks in VPN lockdown mode, CalyxOS partially fixes 1 of them and the others don't touch this since that's not their focus. It's a privacy and security focused site comparing an OS focused on improving those in the OS layer to ones which mostly aren't.

Operating systems lagging far behind on privacy and security patches are definitely quite bad when it comes to security. For example, the official releases of /e/ for the Pixel 7 are still based on Android 13 and do not include any of the Pixel kernel, driver of firmware patches released from October 2023 and later. Eylenburg's table doesn't put much emphasis on this since it's contained within a couple rows which do not adequately communicate how delayed the updates are and how much that matters.

In addition to the official Android and OEM privacy/security patches, there are also major privacy and security improvements in each major Android release. Android also doesn't backport most Moderate and Low severity patches which are no longer given CVE assignments. Most privacy patches are considered Moderate or Low severity if at all. Many privacy improvements also aren't considered to be bug fixes since they're improvements to the intended design of the system. Only bug fixes considered to have a High or Critical severity security impact are backported. The comparison table could cover a bunch of standard Android privacy/security improvements to emphasize the importance of keeping up with the only actual LTS branch.

So, what you are saying is that Lineage has bad security because they are doing their best to support old devices as long as possible?

Interesting position. It is a valid criticism but brings its own problems.
