Eh, wildcard statements like this. Checked your history and you sure like one-liner hit-and-runs like this one. No substance, just vague opinions.
But to actually answer you properly: Heard of OnePlus? They were niche manufacturers curating to geeks like ourselves at the very beginning and THEY USED CyanogenMod ROM! When it was way, WAY more amateurish than GrapheneOS!
When a market is super saturated, the only way to stand out is to experiment and see if something sticks.
This is going to be a very good experiment and can absolutely sell like hot cakes, especially in Europe if they market it well. We absolutely need an – even semi – independent Android hardware here.
Not that I am expecting any meaningful response from you.
