You're right, I was writing this from the top of my head and remembered f2b as simply the banning one and didn't properly check its capabilities for ddos. Sorry for that
I also don't know them in depth, but from what I do know:Lineage is a tweaked AOSP, it doesn't have google apps by default but can use MindTheGapps or microG/e/OS is either their own system or heavily modded android, iirc it uses microG by default (mG is by /e/ i think)Graphene is a privacy-focused android mod that can use googl.e apps, but in a sandbox. Basically a separate space, where they don't have any access to outside data
So basically they all lack google by default, but with different ways to use apps that use google
