I will show you the simplest example when an ordinary person cannot find the truth on a seemingly elementary product: - thermal interfaces (pastes, thermal pads, etc.). Without an expensive testing laboratory, you simply will not be able to evaluate the real characteristics in defiance of those declared by the manufacturer, and most manufacturers (even well-known brands) blatantly lie with their real characteristics.

What can we say about the more complex components included in a smartphone...

You literally need to have a very expensive laboratory for screening out garbage, which is littered with the entire market and which in reality is not worth even 1/3 of the asking price.

The news is primitive in its complexity. Continue studying in elementary school.

This article stupidly mixes up the problems of component reliability (accuracy, stability, performance quality and longevity) and safety. And these are completely different topics.

Security is determined by auditing the firmware of each component part, if they should have them due to their properties.

accuracy, stability, quality of work and durability are determined only by the integrity (and price) of the manufacturer of spare parts.

All smartphone owners are well aware that on the market it is almost impossible to buy a replacement battery of the same quality level (capacity, number of cycles up to 75% drop in capacity, self-discharge rate, the ability to charge faster without a drop in the number of cycles) as the original ones. come with the smartphone. Even at a price that is estimated to be the same as what is installed in the smartphone from the factory. Because the process of selecting a battery supplier is a non-trivial task, like the process of selecting other high-quality components with an optimal price/quality ratio. Gadget developers from any company are hundreds of times more experienced in these matters than ordinary people trying to find cheap replacements for failed components on the market. For a simple reason - they have high-quality special laboratories for testing components (wholesale lots, not individual copies) from different manufacturers in order to weed out quality scammers and work only with reliable suppliers who have passed hundreds of checks.

The average person does not have such an expensive testing laboratory at home, and even more so, he cannot bring it to an offline store in order to weed out outright garbage among different suppliers.

This is the crux of the problem. But here everything is mixed together without any adequate specifics.

Hmmm... There is talk of legislation that would ban parts pairing. Maybe this move is a preemptive action to have some fodder for the lobbying message. Like 'hey, we are doing something good in the right direction... you do not need to try to fix this with legislation'.
Anyway... Independent shops want to use spare parts from broken devices to fix others (and cannibalize stolen devices). So this change will not help them at all.
