Why to offer free under Creative Commons?

I am a supporter of Creative Commons. All my photos are under Creative Commons. I don’t care if someone makes money from that but just to have anyone that needs a photo and for me a citation…
Wikipedia uses 75 of my photos. Many of thme are from famous people that I managed to took pictures of them. One of them my teammate and one of the most strong players Karen Asrian. Sadly he passed away before 2 days. I feel bad about this. Last days I didn’t read any chess news and I received an invitation for group in his memory so I searched for news to see if it was a bad joke or true what I didn’t want to believe.
So I saw that it was everywhere my photo used without any citation to the source.I don’t sell my photos but I would like only a citation for the source.
I found these links below and if I find more it will updated automatically. If someone of also see just post the link to my del.icio.us with notCCAsrian
I tried to contact or to leave a comment to the articles so some of them deleted them but the most disgusting is that armtown had made an link without citation at photo like it was its photo…
So I was thinking why someone to offer anything for free under CC as it is easier to be theft its work?
Just Someone use it in wikipedia after everyone finds it easy and take it without any citation. Even some of theme write via wikipedia like it is owned by wikipedia… Are we ready for CC?
