>Chinese manufacturing has been notorious for quietly undermining the quality of the product to improve their margins over time
Famously Gemtek Technology (https://www.gemteks.com/en/about/about), Apples small obscure modem OEM at the time, when presented with contract to manufacture 1999 AirPort Wifi cards made first batch of complete duds because factory owner saw picofarad smd caps and decided it will be more profitable to for him to GLUE tiny plastic rectangles instead, after all picofarad is like nothing so nobody will tell the difference.
In Poland main opposition candidate for the next prime minister Przemysław Czarnek declared he has solar panels, but he will be removing it because solar is bad (1). He also announced new election slogan "Renewables, shite-wables" (loosly translated oze sroze).

PIS already has one of their men poorly performing function of Poland president. His main election slogan was lowering energy prices, you can guess how that went :-) His latest trick was vetoing super cheap EU military loan because it was conditioned on buying European/Polish equipment meaning none of the money could be funneled to USA.
Apple is more interested in getting people into ecosystem to milk services recurring revenue. They even killed high end top ram options to pump more NEOs.
Nowadays this stuff is standardized by hardware extensions.
Arm Top Byte Ignore (TBI), Intel Linear-Address Masking (LAM) and its fixed version Linear Address Space Separation (LASS), AMD Upper Address Ignore (UAI) still unsecure from SLAM exploits. Then you have security extensions build on top of this like ARM Memory Tagging Extension (MTE).
