Hmm I think it's not only that: "We strongly recommend only purchasing one of the following devices [those are exclusively Pixels] for GrapheneOS due to better security and a long minimum support guarantee from launch for full security updates and other improvements": https://grapheneos.org/faq#recommended-devices
Sure. My point was just that there is value for those who care about security.
Also I have quite a few friends (many Android devs) who have had Pixels for years, and seem happy. My point was that I don't think Pixels are particularly bad. In fact, they are pretty good in some metrics. And very far from being "pieces of shit" like the original comment is saying.
I personally have a Fairphone, which I believe is very good in what it does. But very different from e.g. a Samsung flagship, of course.
This is the list of requirements: https://grapheneos.org/faq#future-devices
