> Well the current Motorola Signature (2026) is 3 times the price of a Pixel.

I understand the sentiment, certainly, but the price difference depends a lot on which model we're comparing to. The Signature will be the flagship from Motorola, and I'll be very, very surprised if it's 3x the price of the Pixel flagship.

Presumably someone who was planning to buy something like the Pixel 10a would be more interested in the non-flagship Motorola devices with GOS support, which are expected to launch later.

Sure. But we're talking about a phone with GrapheneOS. If I need to choose a phone with GrapheneOS, there are cheap to expensive Pixels, and it is not clear at all if there will ever be cheap Motorolas. The Signature is very expensive, just like the most expensive Pixel.
