Open source has a problem where a lot of people demand and request updates, fixes and all that without ever giving back. I am not talking about medium sized companies or even smaller ones, I am talking to a plethora of small one or two human teams that do consulting/freelance development and simply don't have the visibility in the world of open source that others like maybe you and me have. It feels a bit like the recycling problem, it's really easy to do yet only a percentage of the population does it correctly. In the uk, on the defra.gov.uk website, it states that only 16% of the picked up waste is recycling... Why ? How can wr change that?
