It always makes me chuckle when I see companies trying to ship a product (free or not) and realize a few months later that it's not picking up adoption. Then they decide to open source it in an effort to make it popular but of course, they can't admit that, so they always come up with excuses like "We want the community to benefit from it" or "We really believe in open source", etc...

In the end, for most of these products, open sourcing is usually just the last step before the product dies.
