Apple was fined $27 million in France for slowing older iPhones. In any other country, they would have gotten away with it.

France became the first country to make planned obsolescence a criminal offense. Any manufacturer that deliberately shortens a product's lifespan faces up to two years in prison, a €300,000 fine, or up to 5% of annual revenue. The nonprofit HOP, founded by activist Laetitia Vasseur, pushed for years to make it happen.

In 2020, Apple was fined $27 million for intentionally slowing older iPhones and forced to post a public admission on its website for a month. France also introduced a mandatory Repairability Index: every smartphone, laptop, and appliance now carries a score from 1 to 10 showing how easy it is to fix. A national Repair Fund subsidizes repairs to make fixing cheaper than replacing.

No other country has gone this far, and the EU is now working on similar legislation.
 
Ever wonder why "permanent" magnets fade, grow weaker over years?
Me either.

How do magnets work?​

Magnets work because of tiny particles called electrons. These electrons spin and create small magnetic fields. In most things, these fields cancel out. However, in certain materials, like iron, the tiny magnetic fields align in the same direction.
When we rub a magnet on these materials or expose them to a magnetic field, it makes the magnetic fields line up. This alignment makes a magnetic force, creating a north and south pole. Like poles repel, and opposite poles attract. This simple alignment turns the material into a magnet, and it can attract or repel other magnets or magnetic materials. ...

Factors which cause magnets to demagnetise​

  • Heat: Exposure to high temperatures can cause the atoms within a magnet to vibrate more vigorously, disrupting the alignment of magnetic domains. The Curie temperature is the temperature at which a material loses its magnetic properties, and exceeding this temperature can lead to demagnetisation.
  • Physical damage: Strong impacts or dropping of a magnet can cause its internal structure to change, leading to a loss of magnetic strength. Physical damage can also cause the magnetic domains to become misaligned.
  • Electromagnetic fields: Strong external magnetic fields can interfere with the alignment of magnetic domains in a magnet, causing it to lose its magnetism. This is particularly true for magnets made of materials with lower coercivity (ability to resist demagnetisation).
  • Time: Even without external factors, magnets can naturally lose their strength over time due to a phenomenon known as ageing. The magnetic domains within a material can slowly become disordered, leading to a gradual decrease in magnetic strength.
It’s important to note that the rate at which a magnet loses its strength depends on the specific type of magnet, its composition, and the conditions to which it is exposed.

Magnets made of different materials may have varying levels of resistance to demagnetisation. For instance, neodymium magnets are the strongest type of permanent magnets commercially available. While they are very powerful, they are more susceptible to demagnetisation compared to some other types. On the other hand, samarium cobalt magnets have excellent resistance to demagnetisation and can maintain their magnetic strength at high temperatures.
