Edit: Privacy Guides’ take in the Github discussion linked above on /e/OS is quite damning:
"In short, /e/OS will not be recommended until they at least:
- Support verified boot for devices that do support verified boot with third party OSes.
- Ship firmware updates for devices that have not reached EOL.
- Not have any major security regression over the stock OS.
While there is no “anti recommendation” against /e/OS, it is not recommended either because it does not meet basic security requirements…I don’t want to recommend options that I know are bad/questionable."
