Your spychip thing is a made up problem.
It’s on you to debunk the evidence that has been established. You are free to post counter evidence. No one is stopping you.
The distinction is several processor architectures and compatibility.
Luckily we need not upgrade the processor because that is precisely the thing we are keeping back. And we need not upgrade the motherboard in countless different collections of use cases, thanks largely to backwards compatibility.
Go ask them to give your number to the next person they turn away.
I did. One of my local charities already knows what I am looking for. OTOH, they are not diligent. I walked into the shop once and found items they said they would contact me on. This is also not a me problem. It’s a global problem. Your ad hoc idea for just one person will not solve the problem of thousands of pre-spychip machines being needlessly destroyed.
(edit) But I must say it’s a bad idea to for the individual charities to have that task. The public waste management collects the e-waste and distributes to charities what can be used. A DB of what spare parts people need should be implemented at the central point of the collection first and foremost. Getting every charity in the loop would be a good evolution from there but it should start centrally.
