That’s pretty much a swamp cooler

Towels (or other clothes) can stick to the drum and as you pull them out, the balance of the drum shifts and can cause it to spin. If you are grabbing something in a fuller load, your hand/wrist can become entangled and rotate with the drum.

Front-load washers should have a brake for the drum that prevents it from rotating while digging out clothes. Last thing I want is twisted/sprained wrist while peeling towels off the walls of the drum.

I wonder why

You can see the wheels turning
