I do not have a high opinion of /e/OS or Murena. It is LineageOS but "degoogled" which is a meaningless buzzword considering LineageOS already does not contain Google services/apps (you have to install those yourself). Instead it's connected to its own "Murena cloud" which itself uses OpenAI for a speech to text service. But hey, it's not google so it must be okay, right...?

It might be opt in (or opt out? dunno) but this sort of thing should not be a cloud thing, it should be a local service.

It also comes with at least one proprietary app built into the OS and their app store offers proprietary apps with some sort of "tracker detection" thing. I do not trust any "app store" that purports to tell me which proprietary apps are "good."

LineageOS comes with no google apps, no cloud apps, no proprietary apps, etc. It's just a perfectly usable AOSP system. It doesn't even have an "app store" but you can install F-Droid on it. I think GrapheneOS is the same (it supports "sandboxed Google services" but it doesn't include them by default)

As far as I know the only options that exist are LineageOS, GrapheneOS, and maybe non-Android Linuxes if you're brave enough. There used to be DivestOS which although based on LineageOS brought several security, privacy, and freedom improvements, but that project has been discontinued. None of these "degoogled privacy OS" LineageOS reskins impress me.
