Wiki have made their content usable by others, why all the surprise people make use of it!
I think that a big corporation using the work of volunteers to make an extra buck without giving anything back in return is just greedy. When Apple used the Konqueror code for Safari, they gave back to the open source project. Google used the Open directory, but provided some added value with Pagerank and doesn't display ads in their version. If Amazon helped finance Wikipedia with part of the profits, or something, it would be another story.
