Look at the DivestOS site and particularly the posts by SkewedZeppelin (security researcher and lead developer of DivestOS) about /e/OS on their forum and elsewhere.
You can find lots of information about it online beyond that. You can easily confirm that they're consistently way behind on security patches for the OS and browser, set an inaccurate security patch level, downplay it / mislead users about it and massively roll back security beyond how much LineageOS already does.
@GrapheneOS yeah, no, sorry. This is not a source. I asked for a source and you basically responded with “look it up”.
Just because you’ve given me more instructions on what exactly to look up (in this case the security researcher) that doesn’t mean you’ve provided a source. That’s like if someone comes up to you and starts parroting some random political talking point and when you ask where they heard this they just say ‘Biden said it in 2023’.
That’s not a source, it’s a guide to find more information.
@kali This shows how quickly operating systems ship the Android Security Bulletin patches for the Android Open Source Project, which is a small portion of the overall security patches. Around half of the important patches are for firmware, drivers, HALs and the Linux kernel which are not automatically obtained by applying these patches:

This shows /e/OS consistently lags behind around 1.5 to 2 months on this easiest portion of the patches. That's one part of it.
