Let's assume the idea of Open Source is a network of small to medium-sized businesses and individual contributors helping each other out in a mutually beneficial way. A multi-billion dollar corp stepping in by undercutting those businesses' prices and taking without giving back anything of equal value is arguably against the spirit of the idea and a breach of trust. It's technically okay because it is just "accepting a gift" but I'd still say it's exploitation.

Distributing under a NC-license would also go against that idea. (Apart from tipping the perception of "Open Source" towards something more restrictive which is always a bit bitter.)
