So, in some cases, making items disposable can be better for the world.
In the case of the last pair of Sennheiser MD421-II last purchased which both failed after less than a half a dozen uses in front of various reed instruments, slightly after their one year warranty had expired, I did not find their disposable nature better in any way for my world.
When a $300+ microphone that still looks brand new fails and the manufacturer wants near new prices to repair their defect, they have lost me to their world.
