Seen the video. It's a really nifty technology, but the Saw Stop saws are apparently horribly expensive for what they are. It's entirely possible that the other power tool companies aren't using this technology because the licensing and production costs would push their prices higher than they could make a return on, so they can't justify putting it into their products. It doesn't sound as noble as the false sense of security thing, but it's probably closer to reality.

Before anyone starts grumping about safety being paramount at any cost, I'd like to point out you can turn THAT argument right back on to the original inventor. Safety's of paramount importance, so he should give away his license or make it so cheap that companies would be fools to not use it.
