Cringy :/ I used the term "open source" in a sloppy way, too but once somebody complained, I replaced it everywhere with "public source", as that is what I need to reproduce binaries.
I don't know why NVK is pushing this open source label so hard, but it's crystal clear that you can't have common clause in your code and still advertise code of your device as open source.
Some people also reported that NVK blocked them on twitter so they can't comment on any of coldcard twitter posts, and he is against all other hardware wallet devices...
Is this “Open Source”?
No.
