Lastly, regarding your list; that's an awesome list and thanks for sharing. I actually went through the list myself, and since you seem to care a lot about open-source, which I appreciate, I just want to make some mentions to you regarding the list. Just to be clear, not trying to be a dickhead, but I genuinely went through the repos, so I figured some of the things I will list below should be of interest to you.
You obviously don't know anything about licenses like you confirmed publicly, so I would be genuinely concerned purchasing any product from you.
And now all of the sudden you know how to correctly read licenses for list of wallets I posted...
Note that most of the Common Clause licenses you mentioned don't allow selling of code, but it can still be forked and reproduced, much different than what you plan to do.
Hito is only pre-sale so it can't have code released, and Bitbox changed their github page, I can't follow all the changes and some links might be outdated.
I don't know why you hate forked code...it's open source, learn more about it.
