I think the part people take issue with is the idea that water supplies should be privatised. In the video you linked he says that "declaring water as a public right [...] that's an extreme solution". He doesn't say we should steal 3rd world contries' water, but he is clearly in favour of the water supply becoming property of a multi-national like Nestle, rather than managed by the government (i.e. property of the people).

From the Nestle website you linked and subsequent articles and interviews Brabeck seems to have backtracked and now states he believes a minimum amount of water is a human right. He still wants water privatisation though, and must have his shareholders first in mind as CEO of Nestle, not public interest.
