The article states that it lacks analog input, so that might be a good reason.

The article is wrong (at least partially!) - the module they used (the ESP-01) only has a limited number of pins brought out, but the chip itself has a 10 bit ADC on board and there are plenty of modules that bring out the pins. I've been using lots of ESP-12 modules and they're great
But the biggest point for me is the size + the price. Why would one use a Raspi or Arduino to read out some moisture-meter if it can be done with a 3 dollar hardware piece the size of a fingernail?
