If I was looking exclusively for open-source products, I wouldn't let Coldcard's change of license stop me from purchasing their hardware wallet. I called it politics in the past, and I am not interested in it. I certainly don't agree with their development team building on freely available code only to make it unavailable to others once they considered it a finished products. A bitch move! But when people preach the importance of open-source, it's mostly about being able to verify that everything functions as advertised. Even that's something that most people can't do, let alone build upon the code.
