Such a good question, the short answer is I don't know why we have Wikipedia or OSM, I could think of reasons for the specific examples but the heart of the question would still not be answered.

Another example you could have added is pro bono or volunteer work, one answer I could come up with is they wanted too. Maybe my response was a bit dramatic since we do have examples of humans being good to each other.

I'm willing to accept that I could be wrong. What do you think?
