Maybe for other people, not for me. My free time is very expensive. An ESP32 costs nothing compared to the cost of my free time, and comes with wifi and bluetooth, which makes many things simpler. Other solutions whose hardware costs less than an ESP32 cost me a lot of time, and end up being infinitely more expensive than the ESP32 approach.
