The logic must be, "If you have decided to pay for our system-mostly-on-chip parts, there's not much to design, so you can afford to be limited by using only switchercad. This implies "the weeds" from their perspective are other brands of system-mostly-on-chip parts, they don't contribute much "organic matter" and we are beneath being their "beneficial insects" even. but clearly they think > their switchers are the crown jewels.
