If anyone from Motorola reads this thread; the market is beyond ripe for a good shake up. Going full open source and pushing updates & openness, user control and freedom, you will gobble up a good chunk of market share. Make MDM easy & first class (no third parties...), and a ton of corp will roll it out too. We need you more than you think.
None of that sells phones.
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.
