When you upgrade the cpu on a framework laptop, you upgrade the board as well. So Framework owners can upgrade to a 2018 i5 or an AMD or even an ARM cpu if Framework offers it.
At that point I am sure it'll be much cheaper and faster to buy another laptop on sale instead of waiting for framework to make the motherboard with the CPU you want (if they do it at all), and pay extra for custom parts that only fit their latop, therefore locking you into their hardware ecosystem, no different from Apple except the parts are all generic x64 and you don't gain anything other than having in fit in the form factor of their device. The case is not so unique or special that someone would be unwilling to have another device, pay extra for some CPU/mobo laptop combo that only fits in one laptop, and never want another laptop casing again keeping as many of the old part as possible includuing to choose to keep the used chemical batteries in the framework laptop rather than have another cheaper computer with all new parts.
Haven't ever seen that myself ever, most people don't care, they just don't want to replace the machine if it still works if that counts, but nobody is using a classic all original parts device or seeks a classic HDD for their old computer. If you present them with a better one though, I bet most would be jumping for joy, but you have to make sure its "better" to them.
