We talk about planned obsolescence when a manufacturer consciously makes design and manufacturing decisions that results in a limited product life. This doesn’t necessarily mean that products are made to break after a certain period. If a manufacturer designs a product in such a way that it cannot be disassembled, or if they decide not to make spare parts, repair information, or software updates available, they are making a deliberate choice that result in a limited product life - the product becomes obsolete due to the manufacturer’s decision not to support its prolonged use.
