One thing I don't see mentioned with any of these discussions is that this massively increases the cost of using different kinds of blades on the saw. If you need to use a specialty blade that's a smaller diameter, it requires a matching special size safety cartridge. Dado stack? Another, even more expensive cartridge. I know most people typically have one blade on the saw and never change it or if they do, it's just another of the same size, but for those of us who do regularly swap out blades that aren't the standard 10" x 1/8", these types of regulations add both significant cost and time/frustration.

I'm all for safety and would love for there to be more options for this kind of tech from other saw makers, but I personally don't think regulation is necessarily the right way to do it. Just like there are legitimate cases for removing the blade guard, there are legitimate cases for running without this safety feature, especially one that would require several hundred dollars more investment even if the safety feature is disabled (On SawStop, you physically can't mount a dado stack unless you buy a special dado stack cartridge).

And if SawStop really wanted to improve safety for everyone... well I find it rather telling that they'll only open their patent if the regulation becomes law. Since they're effectively the only ones with the tech, with the regulation passed, buyers instantly have only one option for however long it takes for competitors to come to market with their own (which they'll be hesitant to do based only on a spoken promise by the patent holder). Instant pseudo-monopoly.
