I'm at work so no time to actually review but I think the article which makes that statement is incorrect.

All other parameters being equal, reduced unsprung mass does not
require reduced spring rate. Actually, reduced spring rate in both cases lowers the resonant frequency of the suspension system which negatively affects the system's ability to recover quickly from a perturbation (bump). Traction is lost during that increased time required for the wheel to reverse direction and regain full contact with the road surface.
I'll wait until this evening to find out how wrong I am but for now, I'm going to stick it out there for consideration.
