Dijkstra is often quoted (though no clue if he actually said it) with a similar expression "Computer Science is no more about computers than astronomy is about telescopes."
CS tends to focus more on abstractions about data and algorithms, rather than the data specific to a particular field.
Yes, as the others said, the study of different ways to compute.
For example, from the article, "The Eyebrowse project is motivated, in part, by the fact that as researchers, we have no idea how people actually use the web." That's not about computation, that's human-computer interaction, which I think of more as applied psychology melded with graphic design. While there are opportunities to advance the field of analyzing large data sets, that's still more in the realm of advanced statistics than computation.
