I suppose a company can not be PURELY open source software & hardware, otherwise making a profit would be very difficult,
Adafruit.com says they made a lot of money while everything they sell is open source. There was a good New York Times article about it.
Why would I use the OPenSource info to build and populate an Arduino board when I can buy one for less than $20?? If I want to make a modified fork of that design to provide special functions, and I am going to make 500+ of them, that's different (I'm thinking of doing that right now)...
