Considering there's a finite punt of resources on this planet, disposable things really rub me the wrong way. I love the price point but the irresponsibility of marketing things like this as disposable irks me.
If it’s mostly made out of silicon and metals, it is not much different from natural rocks, just at a lower level of entropy. If the energy source is renewable and the supply chain sustainable, it is not that bad. Like clay tea cups in Asia, disposable isn’t always bad.
This isnt a new price point, Chinese companies have been selling $1 Free International Shipping Bluetooth Buttons for a good while now, powered by unnamed Chinese homegrown silicon (Unisoc if its "hiend", freqchip if you like newcomers https://github.com/qdfreqchip/FR801x-SDK). Same way audio BT dongles are $2.
