I'm not sure what you're going on about. Traumflug said "Note that these MOSFETs (not exactly Transistors)...". MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor. Transistor is in the fricking name so no one can say that they are not exactly transistors. BJT also have transistors in the name. They serve very different purposes, but they are TRANSISTORS.
We're using them as switches. We don't care about amplification and gain and distortion. It's essentially irrelevant when it's either on or off.
And I'd also challenge your assertation that mosfets are only used as amplifiers with small signals. Amazon has 5,600+ examples of not-small-signals using MOSFETs. They're a different category of MOSFETs that what we use, but they are still MOSFETS none the less.
