Not OP, but price and availability. Before about a year or two ago, it was a cheap-and-cheerful way to put some smarts into any project. Now it's impossible to get at twice the price, and the alternatives aren't quite there yet in terms of software support.
I still like reading about the projects you can do with it though. I find it inspiring for my own side things (even though fewer of them involve the RPi itself -- you can push microcontrollers really far these days!)
To get things clear, I love RPi and use rp2040 for lot of my projects. Use to go with RPi for small projects and now I have lot of ideas and unable to get a RPi for the last 1.5 yrs
Yeah it's been crazy out there. I've been trying to adapt by pushing into the ESP32, which has the WiFi connectivity I need and is cheap and available. But if I had built a business around RPi (as my old employer almost did -- they dodged a bullet there) I'd be in big trouble.
