@ryo That still doesn't change the fact that even those ThinkPads and ToughBooks will inevitably fail. I'm not against using old computers. If you are able to use a 2009 Thinkpad as your daily driver, then that's great.
I also kind of feel obligated to support these alternative hardware manufacturers, so there will still be that option when using old Thinkpads becomes next to impossible (it would probably take decades but still).
Also, think of a scenario where more and more people wake up to what hardware manufactures like HP, Dell, Apple, Nvidia, Intel, AMD, etc are doing and learn that they can just use older computers if they use a lightweight Linux distro. Prices for older computers would skyrocket. I see the same thing happening with used cars now that they are literally putting DRM (with some countries even mandating it) in cars. The only difference with computers is that there aren't that many countries mandating backdoors in computers (yet).
Basically, I just see using older computers as a short-term solution to a long-term problem.
