"The tech" is actually pretty widespread. It's just putting weights at the end of lines and spinning them. A lot of satellites will be spun up for stablity, fired into higher orbits, and then de-spun using weights on lines that extend like this and slow the rotation rate like a skater extending their arms to slow a spin. I think it's a great, great idea to build it, just put it somewhere else to test it. It's not designed for LEO anyway, and as electrified tether experiments have shown, the Earth's magnetic field can really screw with a vehicle like this even if there were no satellites for it to endanger.
