We open sourced our air quality monitor (firmware & hardware) under CC-BY-SA. The SA (share-a-like) gives quite a lot of protection in regards to the concerns that the author rises as most companies that would take our source code would not be willing to keep it open and also probably not so keen to attribute us as originators. I think what also many people forget is that the source-code is actually only a small part of business success. In my opinion the network, reputation and community that a company builds has much more value than the actual code. We went fully open source hardware more than 2 years ago and it was probably one of our best decisions as a company.
