Why do manufacturers not insist on the usefulness of maintenance?

It’s not their main concern. They are busy manufacturing very technical products, designing new models and passing them through demanding certification tests in a market where competition is fierce!

Moreover, if a used paraglider flies less well, the pilot will be encouraged to buy another one more quickly, which is good enough for the business!!!

Planned obsolescence ?

Far be it from me to say that it’s planned obsolescence, but it still looks a bit like a slowing down computer or smartphone…
