The distributed published nature of open linked data is vital to the health of the datasets. It means that each dataset is curated by a community that cares specifically about that data. However, this argument of distributed publishing and curation is in my opinion not only valid in the public space, but also for data and content sources within enterprises, which with their many departments and teams form webs of their own. The scientist running an experiment for example is who knows best about the resulting data, so let her curate it. The sales department has the best understanding of their sales data, the product development team of their knowledge base.
In the end this is all similar to the discussion about open data (as in data on the Web) and linked data (as in a technology for data webs). They are complementary, but each of them has its own and independent value proposition.
