I wonder if some of it is a reaction to "growing out of" the narrow AVR ecosystem. When you have a billion options, it's neat to pick something percieved better "because I can" I have a project that uses the now-deprecated (officially sold through, but you can find an awful lot of them of questionable authenticity on Aliexpress) Teensy++. The Teensy++ was always expensive for what you got ($24 for an AT90USB1286), but now you can get ARM and RISC-V boards with comparable or more RAM, flash, and GPIO counts, while bumping from an 8-bit 16MHz CPU to a 32-bit 100+MHz CPU, and still pay less money. I've been fiddling with the nanoCH32V305 just because, at $6 per unit, I could put aside a fair stock of boards if I decide in a few years I want to build more of the project.
