Socialism

On the design side, while PO does happen, there's a huge amount of deprioritising durability and user serviceability that all come under an umbrella of "consumer buy another one".

Like, it looks like PO, but isn't. If you can reduce weight by 10% but reduce user serviceability, most companies will take that choice easily.

That said, my last two phones have bricked themselves with 3 months of being out of warranty. My last one was a Pixel 3 that bricked due to an update (the pixel 4s that got bricked by the same update got replaced by Google, but my pixel 3 did not) (it was kinda random, not every phone with that patch got bricked, I think it was a minority)
