When Doug & Spencer started working together, this would have all been covered in the contract signed by both of them I imagine (if not, they're both a bit silly).
As such, I highly doubt Spencer is doing anything 'illegal', why would you put your business at risk?! Although morals are another subject entirely.
Interestingly, the new Finnish Darkglass pedals still seem to have the relay bypass added by 3Leaf when Spencer started making the B3K. I wonder if the Finnish relay is that design or a new one
