Framework laptops aren't really repairable in the same way that old Thinkpads are. Maybe that's good, maybe not, but replacing an entire motherboard every 3 years isn't all that different from replacing an entire computer really.
Wait, are you saying they don't offer the full HMMs and FRU list like IBM/Lenovo did/does for ThinkPads?????
IBM HMMs, or creatively named Hardware Maintenance Manuals, were written so that if all steps in the document were performed from start to end as written, the laptop would be a pile of FRUs or Field Replacement Units, so that those FRUs can be inspected, discarded, ordered, and replaced, and then the process can be done in reverse to produce a working unit.
Why - I mean I think I know why - they likely don't have enough control and/or influence over parts suppliers to be able to publicly expose those data unlike the Big Blue - but why...

In what way can you repair and old Thinkpad that you can't repair a framework?
To add a data point here, my Framework laptop is 3 years old and I have no plans to change the mainboard anytime soon.
Also, you don't change its motherboard, you change the mainboard (for my laptop, it's the CPU/integrated GPU + memory sockets); this is unlike changing the entire computer. Then, you can reuse the replaced mainboard as a server if you wish to.
This pales with my experience using a Macbook Air whose motherboard failed. I did have to replace the entire computer.
