although just a cursory look at the drama surrounding it is reason enough, my real reason is pretty simple: the hardware costs just way too much.
a phone should cost like $100, max. that's an easily breakable thief magnet and you should put in as much effort as possible to treat it as a fungible device. you break or lose one - no big deal, it's encrypted, restore from backup and keep on truckin'.
I can lose/break/gift like 6 or 7 competent devices (SDM680/845/etc, 6 GB RAM) before I even get close to the price of one used Pixel. hard, hard pass.
it was pretty bad. the "protagonist" was as irritating as they come. evacide, doctorow and co. were super-underutilized, I imagine a huge chunk was cut out to make enough room for mr. annoyance and his forced parables and non-sequiturs.
I understand some things had to be dumbed down, but this was really, really bad from every angle you look at it.
