Prior to the pandemic, I rarely had an issue with obtaining a Pi 4. I would usually get them at Adafruit. If they weren't in stock, I would just wait a couple of days and buy what I wanted when they were. I didn't have much of a need for Pi 4s in the past, but that has changed. I could use 3 or 4 more Pi 4s. Thankfully, I have plenty of Pi Zero W's. In the past, Adafruit put a limit of one Pi zero (per configuration) per order. Every time I ordered something, I added a Pi zero W & a Pi zero W with an installed header. Right now I've got almost a dozen Pi zeros for the projects I'm working on. But I do agree with you, they could have sold as many as they made.
