I have no data on this but I would assume people buy new phones for their features - which, these days, probably comes down to camera and media editing. Maybe gaming. Apple has a trade-in program for year old devices. Google too. Who cares about updates? 7 years, 15 years - most devices are probably replaced by their upgraded siblings before 7 years have passed. Again, I have no data on this but I don't meet many people with even 5 year old devices.

I sense some level of tin foil hat thinking there. Go ahead and dig through the AOSP code. It's open source. Many others did. No backdoor has been documented so far. Maybe you'll succeed.
I understand that it seems weird that a company such as Google (which is known for data collection) builds a priavcy friendly phone (well, after a few tweaks here and there, anyway). But as mentioned above the google OS on stock pixels is only based on the AOSP. It's not the same. All the bad stuff, if you will, stems from the closed source part - that's where the real Google lives, hungry for data. Graphene OS, however, is built upon the AOSP code. Which is open source. No backdoors.
Also, are you trolling?
