In some cases, but a product must fulfill its core purpose. If a SSD intentionally dumped data and self destructed at a set time, that would be disastrous for the brand. Same way a car doesn't adopt planned obsolescence by blowing up after 200k miles.

Other than "intentionally" (which we cannot know and makes no difference to whether you lose your data or not) that is literally what these SSDs are doing, and no SSD brand has been destroyed over it.
What more could a manufacturer do to be "disastrous for the brand" than literally build an ssd that stops working after 40kh? Because this does not seem to qualify for you
