No, that's not at all what was said.

Pixel 7 is a fully supported device with Android 16 QPR1 available for it via the stock OS. /e/ is on Android 13 on the Pixel 7 without the kernel, driver and firmware updates released for it from the Android 14 launch and later. /e/ is a fork of LineageOS with drastically worse privacy and security.

LineageOS rolls back the security model and features a fair bit but does it far less than /e. LineageOS doesn't implement major privacy and security enhancements so a comparison of non-standard improvements in those areas is going to show that. LineageOS lags behind on providing the AOSP and vendor security patches, but far less than /e/.

The table covers the patch delays for both AOSP patches and device patches. It's showing how far behind they are on kernel, driver and firmware patches released for a device, not anything to do with end-of-life devices. Being multiple years behind on those patches for the Pixel 7 on /e/ has nothing to do with supporting an old device as long as possible.
