It's certainly a provocative use of the language. I believe they are making the case that fetishistic hoarding of historical documents is both, only available to those with a means of wealth created through probably exploitation, and in an of itself an aspect of western/euro-centric ideology and its propagation through colonization. I tend to think the hoarding mentality is more base then that (I've watched squirrels before) but I think the argument that hoarding knowledge specifically is certainly a more amorphous problem.

Yes, they are just making the claim that the information should be available. They are putting it into their own contextualized argument framework.
