Just raise the price already. The market price of a Pi Zero 2W is about $70 right now. For my application, I'm happy to pay it, because the alternative would be spending a month of skilled developer time designing a daughterboard and porting software to a different SBC. If Adafruit actually succeeded in preventing scalpers from buying up the supply, this would mean misallocating boards to projects where a dozen other boards would have worked just as well.
