:FR: :GB: :DE: Migrating from FP open to LineageOS on an FP2, some questions

Why? (Honest question)
What’s the benefit of microG (which tries to mimic Google services so Apps relying on Google services might perhaps work without them) when you want to go Google-free and don’t want to use Google Apps or the Play Store?

I mean, I use LineageOS for microG myself, but @Muselaar: Do you use any Apps from the Play Store on your Fairphone Open OS (via Open GApps or the likes)?

As does regular LineageOS.

Honest question because I didn’t care much about /e/ yet … What does /e/ do better in this regard than regular LineageOS?
/e/ was even based on LineageOS at /e/'s start (Android 7) … have they emancipated themselves from LineageOS now going to Android 9?
