My pixel 5 just stopped turning on one day about 2 years in, and my pixel 7 pro had the volume and power buttons fall out about 3 weeks in (not due to a drop, after googling it's apparently a very widely seen issue).
The service with iFixit was unhelpful, they told me "We keep seeing this and Google says this is wear and tear. We can't submit it for a warranty repair, and if we try we end up eating the cost". After finally complaining on twitter I was contacted by some support person who said to give iFixit this email and they would fix it. They still refused, and after a few more rounds of interactions like that I eventually bought some replacement buttons on Amazon, popped them in, and put a case that covers them on it. I'm fully expecting this to randomly die some time before 2 years is up.
Combine that with Google's extremely strong tendency to abandon everything, promises like these seem well, worthless.
Meanwhile my daughter is using my wife's old iPhone from 8 years ago. My Samsung note 3 and my s8 still boot up and work just fine (though I cracked the screen on one about 5 years ago). It's just so obvious that these phones are very low priority to Google, while other companies base their business around their phones.
Some things just aren't feasible to collect evidence for. You would need access to their private communications to find evidence. So your basically giving a pass to any maleficence done in the dark.
