This article is lying or perhaps I am misunderstanding.
The article states: "Cherry switches are linear — by definition, not tactile. They lack a click leaf, which is required for tactile feedback."
I have used and built several mechanical keyboards with Cherry MX Blue switches. They _are_ non-linear and _do_ include a click leaf which gives the Cherry MX Blue [1] its characteristic "bump" feel and click.
