For a lot of open source frameworks and libraries it's not a financial decision. We need them for what we're doing and we're happy to share them with others.

For a lot of open source frameworks and libraries it's not a financial decision. We need them for what we're doing and we're happy to share them with others. If we're lucky then we'll get some help from others on them. Some libraries that provide an interface to a commercial system will be given away free by the company to make it easier to get people using the system. Once they're using it they can then be converted into a regular income.
