> It's amazing how much they've lost the tinkerer audience over the last few years.
They haven't lost it. Their goal was to kickstart something and they succeeded beyond their wildest dreams. The space has moved - a usable computer now demands a lot more than the original Pi, and they realized that - this is why their tinkerer platform is the RP2040 family. The market is very healthy and the ESP32 family has a huge space.
What RPi brought was the idea that a platform with good software support would allow for a revolution in the space above the power of an Arduino.
