I bought my pixel 7 early this year because my s20's screen broke and the cost to buy a new one to replace it myself, which is not something I think most people would be willing to do (instead paying even more for someone else to do it), exceeded the cost to buy another S20. On top of that, the moment my 3 year old, perfectly working phone had anything other than a pristine screen, it had zero trade-in value and basically encouraged me to throw it in a drawer or the trash. This was literally Samsung's flagship phone only 3 years prior.
That could have probably been mitigated if the s20 remained relevant for more than a year or two and there was a mature parts market that made it feasible to upkeep rather than scrap.
