Questions about moving to Lineage OS on FP2

If avoiding Google as much as possible is an aim of you then you might also have a look at /e/.
One of the aims of /e/ is exactly to avoid transferring data/information to google while at the same time trying to address non-tech-savvy people.
An advantage may be that updates are not published as often as with LineageOS and they are tested before being released. On the other hand /e/OS is still in a beta phase (but IMHO stable) and current official version for FP2 is still based on Android Nougat (v7).
