Unethical is making the tools such that the battery case is incompatible with any other tool. FYI, all tool batteries are just a bunch of 18650 style cells (little bigger than a AA). They are literally all the same inside. Because of greedy corporations, we have to buy different batteries for different tools with different chargers. You know, like back before all phones were usb-c?

There should be a universal tool battery spec. Instead they are all a little different so they can make money and we get tons of e-waste.

I believe in the eu they have standard batteries. It’s just us schmucks in the usa that get this bullshit.
