One of post on thread mentioned by OP mention the source.
The OP includes two links; one to nvK's profile and another to his own review of the "open source" (I'll get to that in a minute) blockclock. No mention of the cease and desist without me digging, and still no proof other than the claims of someone who's trying to profit off nvK's code. If this thread is really about the cease and desist, why didn't dkbit98 provide a link directly Mitchell's post? Could it be because he's merit hunting like usual?
Common Clause allows anyone to download and use the code, a true "DIY" project wouldn't be restricted from using the code. What the licensing doesn't allow is someone to sell kits that require the code. That's a direct violation of the licensing. The licensing chosen by Coinkite is there business and their business alone. No one is putting a gun to your head and forcing you to buy their product. In fact, you could
build your own ColdCard and use nvK's code to operate it. You just can't sell them.
although OP never say "closed source".
Note the post right below the OP. There are many on this forum who aren't proficient in English and haven't learned to read between dkbit98's lines. He has been spreading fear and misinformation about ColdCard for years by using phrases like "anti-open-source." He won't correct anyone who then refers to them as "closed-source" because his beef with nvK is more important than facts.
And you giving him positive feedback now is making me think that you are connected with him in some way.
I'm not, but so what if I was? Are you going to also give me a red-tag based on your biases and lack of understanding? One of us based our review on experience with his products and the other based it on butthurt. I'll leave it to the community to determine which is more helpful.
But let me ask you a question; how have you contributed to bitcoin? Making a bunch of comparison threads on the forum? No matter how much merit you earn here, nvK has done more for the growth of bitcoin than you could ever dream. Your dogmatic view of "open source" as some holey grail, and opinion that all participants need to strictly adhere to your religion only demonstrates your lack of technical knowledge and a lack of understanding of how businesses are operated.
