> I don't understand why it took LineageOS so long to update to AOSP 17, while GrapheneOS managed to update to 17 in just 3 days.
Here's a hint: GrapheneOS has paid developers working on it full-time, while LineageOS is done by people in their spare time. Also, GrapheneOS has a collaboration with Motorola and through that gets for instance early access to security patches, and probably other things as well. And lastly, LineageOS supports roughly 10x the number of devices. It's significantly easier if you restrict yourself to Pixels.
GrapheneOS doesn't receive early access to security patches via Motorola. We receive those through a different partner. We were already doing security preview releases prior to Motorola giving us access to their repositories which don't contain those.

Just for clarification (your points are very valid): the GrapheneOS developers have stated on several occasions that they getting embargoed patches from another OEM than Motorola.
LineageOS code can update pretty fast, but the problem is they want to do refactors, and also that bringing up a hundred outdated devices is difficult.
