Maybe we find out the profit from including ads and spyware isn't so much, and it all turns out great? Moto sees the chance to get on the right side of consumers and sells phones as a result.

Is this ...conjecture? I will make two points.

1. They might want to market the phones to security-minded people, say the banking sector, governments, etc. They have the funds to spend and have high stakes.
2. GrapheneOS as it is now already gets flack for supposed backdoors in Pixels. The common response to that is that independent audits have shown that GrapheneOS phones are resistant to common penetration and surveillance attacks. No matter the hardware, independent audits are what makes people trust GrapheneOS. If future audits revise that trust, the community will just move forward.
