There's a footnote, attached in the wrong place, that explains the use of word "Heresy". It's used in a similar sense as "revolt", in the context of contrarianism. In that sense, it is "heresy" -- not the current norm -- to put the user in charge of constructing the view of information in a system. It might be true. Anyways, it took me a bit to understand what the author was saying, and the articles would be a lot easier to read if they used plain English. The articles are quite contextual and people with a different frame of view might interpret them differently, which is not good communication.
