nRF51822 : open source firmware ?

[fredmar]

Hi, I am looking for a Bluetooth Low Energy Soc based solution like nRF51822, but I'd like to have an open source firmware solution...

Do you have that kind of solution, nRF51822 solution or another ? (BLE and open source firmware)

This question is purely curiosity on my part: What drives the desire for an open source solution over a closed solution? I don't see a product requirement that would drive it so I can speculate that it is either a) You or your employer want/need to be able to control the source yourselves; b) A strongly held belief that all software should be open source
