My /e/ exit interview

Take for example the Teracube 2e that /e/OS is currently selling: https://murena.com/shop/smartphones/brand-new/murena-teracube-2e-emerald-na/

Here are the prorprietary vendor blobs that are being shipped with it: https://gitlab.e.foundation/e/devices/android_device_teracube_emerald/-/blob/v1-r/proprietary-files.txt

Note the line at the top denoting the version those blobs are from:

Extracted from full_yk673v6_lwg62_64-user 11 RP1A.200720.011 p1k61v164bspP16 release-keys unless pinned

More specifically this part: RP1A.200720
That is this version of Android: https://android.googlesource.com/platform/build/+/9d2242d67e673ed357812999705a7b91be3a1f58

Note the date:

Here is the kernel too, note the version it uses: https://gitlab.e.foundation/e/devices/android_kernel_teracube_emerald/-/blob/v1-r/Makefile

4.19.127

Here is Linux 4.19.127: https://lwn.net/Articles/822424/

Note the date:

Is it really acceptable for /e/OS to be selling devices that are 2+ years behind on kernel and vendor security patches?

Edit: these other devices they’re selling are also end-of-life (only the oem/vendor can provide firmware&vendor security updates)
