There are advantages to ABP, for devices whose security is not essential.
It's a simple TX without RX, which allows simpler devices, with inefficient antenna.
The communication is shorter, so the battery is less solicited.
In addition, the main competitors allow to make this strategy (Objenious, TTN, ...)
