Seems like Foundation benefits substantially already from Coinkite's work, and continue to do so. Probably wouldn't exist at all without Coinkite.

License clearly allows them to build on top of Coldcard firmware, so long as they are also adding value. It's disingenuous to claim it's not in the realm of open source, because it obviously is.

If I were to **actually** steel man the probable logic for Coinkite's decision its that they wanted to contribute their code and let it be scrutinized, but they wanted some assurance against a much bigger and better capitalized manufacturer doing a full clone (or even many smaller ones cloning and distributing on Amazon potentially putting users at risk).

I doubt there would be any issue with other firms producing products with improvements or different security models. Just seems like a personal issue between Foundation and Coinkite, and Seth is pressing it as a negative marketing campaign which just fuels the fire.

I thought Foundation devices looked interesting and I was open to buying one, but this marketing approach has left a sour taste. Probably won't ever buy from them now, but good luck to you all 🏳️
