I absolutely second this. "IoT" is a keyword to furnish up cheap hardware where the price of physical switches would have harmed the profit margin too much. This is not really ironic: Physical switches (with a price of probably 0,2 USD per component) are more expensive then SoC having Wifi implemented. Also it's cheaper to hire software-only developers to do as little hardware engineering as possible. It's all about cutting the price per unit down.
