Image comes from the monstrous work the Asahi Linux team did to get Netflix working on Linux on ARM Macbooks: https://asahilinux.org/2024/01/fedora-asahi-new/
It depends on what you'll run on it.
LineageOS in itself is good/private.
However the GApps/GMS are not.
I'd recommend replacing GMS with MicroG if you need that for the apps you use,
which still talks to Google,
but in a minimal way.
YouTube isn't private either,
but Grayjay/NewPipe are.
