> Assuming Framework's thesis bears out, that their customers will actually upgrade their laptops piece by piece when given the opportunity to do so, rather than buy a whole new laptop, then it's a matter of increasing their market share, especially through corporate IT contracts.
You can't upgrade a framework laptop 'by piece', unless you mean swapping in more ram or a bigger/faster ssd. Not really any different from other mainstream laptop vendors in that regard. The CPU is soldered, so you can't upgrade within the CPU platform generation, there's no drop in replacement options for the screen except the IPS panel they ship with (so no high dpi options or OLED/microled, no high refresh rate option, etc), and only proprietary recessed USB-C dongles for changing ports. It's a joke product.

Sounds like your usecase calls for a desktop system then, I know plenty of people still using 2013-2015 retina macbook pros for daily development work and they do just fine. There wasn't much performance improvement after those years until the apple silicon transition, you could get 6 and 8 core coffee lake CPUs on the last year of the intel macbook pros but they were essentially unusable for laptop usecases since they had to aggressively thermal throttle and nuked battery life as a result (something that is an even worse problem now with Intel and AMD both juicing core count and clock speeds to chase benchmark wins rather than improving perf per watt and overall system usability).
