This would only fall under our definition of planned obsolescence in cases where regulations about old diesel cars were part of some conspiracy to make people buy more cars, and not motivated by pollution concerns. As such, I've removed it.__Gamren (talk) 12:22, 21 November 2020 (UTC)
mRNA vaccines trick the body into producing antigens, but there is no real enemy for the immune system to keep these antibodies in evidence so that it can immediately produce antigens again in the event of a new outbreak. Where normal vaccinations keep their effect for decades, here only half a year should be possible. This is planned obsolescence in vaccinations. Here a study about the fast occurring inefficiency: https://www.thelancet.com/journals/lanepe/article/PIIS2666-7762(21)00185-X/fulltext Pege.founder (talk) 10:33, 30 October 2021 (UTC)
For decades car headlights could be easily opened and the main wear parts, front glass and reflector, which get broken or blind in use, were exchangeable. Often there were several producers of replacement glasses for one make of a headlight. Since around the year 2000, the front glass is in fact plastics and glued together with the case of the headlight. So there is no way of non-destructively opening the case, and there are no spare parts available. Additionaly, the appearance of the whole headlight is often protected by copyright, so no other manufacturers than those authorized by the car maker can offer replacements. Electronic modules for Xenon oder LED technology are also unaccessibly located inside the case. 2001:16B8:2CEB:9200:CCCF:C54:1D10:5AF9 (talk) 09:40, 14 August 2022 (UTC)
Should the introduction include "or might be perceived as unfashionable." The reference following this sentence is about durability, which makes sense. Falling out of fashion doesn't make goods stop being functional. Are people forced to buy a new version of a good just because the old one is no longer aesthetically appealing. What is the consensus among those who study this subject?
How about this reference? It does include fashionability. https://www.tandfonline.com/doi/full/10.1080/19397038.2015.1099757
