It has one Gyro for stabilization like any other gimbal controlling the 3 axes: roll, pitch, and yaw. The other "3 axes" are just 3 accelerometers.
This is great, but I highly doubt that a petition directed towards the manufacturers is going to do anything. I'm not saying the petition isn't a good idea, it just shouldn't be directed towards the manufacturers. Rather it should be directed towards government bodies that regulate technology, like the FCC. Not sure that the FCC can do anything, or any other government body can for that matter, but I'm not exactly optimistic that a petition sent towards the manufacturers is going to have an effect. It's none of the concern of the manufacturers whether or not the artists vision isn't truly realized, in fact they probably don't care.
