How have you arrived at the extremely subjective designation: unbiased 

An opinion isn't inherently objective, irrespective of opinion maker, 
its at best a subjective claim.

Is the world perfect? No, but we do have some sense of what things are 
albeit subjectively.

So, just because the Web started off as an Information Resource Space, 
it cannot evolve into a Data Space? Which also enables it to evolve into 
a Knowledge Space.

Anything can be "Junk" just as another subjective moniker, like 
"Beautiful", "Ugly" etc.. Linked Data doesn't fix subjectivity.

Linked Data helps us extract "What", "When", "Where", and "Who" from 
streams of data traveling across the InterWeb. It also contributes to 
the process of computing "Why".

I would like to agree with you on "choice" but context is completely 
mangled i.e., you opening salvo re. "Junk" was 100% subjective but 
presented as objective by some strange triangulation to "unbiased" etc..
