I’m not exactly sure what point you are trying to make. The specs to which you refer are also specs which the component are _rated_ at. But that’s still only a (very high) % of components. Issues do arise with individual components. Unless it is wide spread, it is not a scandal. I have worked in the industry as well as do it as a hobby. You have a very rose colored view of it.

Lemon phones make it into the hands of consumers. I had one myself a few years ago where it overheated and shut down. One offs don’t make the news because you bring it in and it’s swapped out.
