Edit: I read some more as well and it seems you are correct, adding a restriction for commercial use cases makes the code not respect open-source rules anymore. I was genuinely not aware of this beforehand. I will give this some more thought and see if we want to go the source available vs fully open source route. My fear is exactly the one described above; i.e. someone forking it the next day and launching a competitor.
Would be honestly really great to hear some opinions of why you think open source is better vs source available.
IMO you will get a lot of resistance to reproducible source available vs open source. And I think you should do what works for your company.
I don't care so long as I can verify that it's good and even more with a product like this I don't think it matters.
There are 2 parts of the product the ring and the software. The issue is the physical ring can be anything even a cheap EMV card. So that means someone can come in and take your work and make a cheap ass product using your code.
For things where the software is the product (electrum) then I want open source. For products where someone can take your code and create a similar product for a low price and sell it for a lot then reproducible source available is fine for me.
I will also say that this is probably not going to be a popular opinion here, but it is mine :-)
