My bad, I thought you were making a joke about Pika saying “planned obsidence” instead of “planned obsolescence.” I did not realize you were making a genuine inquiry.

Planned obsolescence is when businesses intentionally design a product to become useless after a period of time.

For example, imagine a high end camera company that also sells replacement parts. They change their lens shape every model, and only keep the most recent models’ lenses in production. When an older model’s lens inevitably breaks, the customer cannot buy a replacement, and thus has pressure to buy s new camera, and the company hopes that most customers will buy from them again.

We see this in tech with smartphone companies only giving OS updates for a few years, causing older phones to go end of life, so even if the phone is fully functional it needs to be replaced. Again, the company hopes the customer will again buy from them rather than going to a competitor (who is likely running the same scheme.)

OP suggests Microsoft’s TPM requirement is there to force new computer sales, which will include a purchase of a Windows 11 OEM license bundled with the PC.
