Is the source open and can anyone read it and verify? Yes, that's what's important for me, as a wallet owner. Do you want to learn more about bitcoin hardware wallet softwares? You can read every single line of their source code anytime you wish, so, you can learn from them and come up with your product if it's better and not totally based on their source code.
Supporting this point. Consider the perspective of an ordinary wallet user whose sole concern is the availability of code for scrutiny and verification. To such a user, the Commons Clause attached to the MIT license accompanied CC product appears to be nothing more than a sheer casuistic. From their standpoint, all they seek is open access to the code, making the presence of the Commons Clause seem irrelevant.
