The problem isn't with the artist doing a one-off project involving a microcontroller. It's the Arduino "experts" who write blogs, create videos, and dominate forums with their accumulated nonsense. They posit themselves as authorities in the space, newbies adopt and echo whatever rubbish they make up, and the cycle continues. They get very defensive if you try to correct them, even linking directly to documentation supporting it.

If you're going to write a blog about how the ESP32 doesn't connect to the strongest AP so you need to pin it to a specific BSSID in your router settings... Maybe you shouldn't be writing that blog. If you haven't taken at least a moment to check documentation and see that the behaviour you want is already an option that can be selected by changing literally one line in your ESP32's WiFi config. Instead this pseudoscience proliferates.
