That's a legitimate strategy for some Amazon trinkets but CPUs are a major purchase for most people such that they won't likely let them sit in a closet beyond the warranty period.
I would guess Intel is counting on the fact that most people are not knowledgeable enough to pinpoint a defective CPU being the issue when the computer starts crashing.
Heck, even as a SWE building my own computers for almost 20 years, I still have no idea how to properly diagnose a hardware issue when it arises. Beyond checking for explicit errors in journals/logs, and the usual memtest/BIOS update/reinstall the OS from scratch, I resort to replacing each component one by one until the issue disappears. But it's time consuming, and sometimes quite costly. I suspect most people simply replace the entire thing if it's not a prebuilt PC still under warranty.
I was similarly peeved with AMD a few years ago. There was a window of time where an AMD chip would not work with many deployed motherboards. AMD would ship you a loaner, outdated chip so you could boot the motherboard and apply the latest compatible BIOS.
Knowing this, I felt confident to purchase a certain configuration. Parts arrive and I reached out to AMD support for my loaner chip. They gave me the third degree. Insisted I provided documentation of previous attempts to reach out to the motherboard manufacturer before they would lift a finger. So, reach out to the manufacturer and say I am an idiot who cannot read the compatibility warning slathered all over their product material? I was furious at what was an obvious roadblock to not deliver on their support promise.
