It depends on how you define the "fight."

In the Nielsen days, two things were happening:

1. People were creating quirky, whimsical, odd corners of the internet for nobody but themselves. Art.

2. Entrepreneurs were starting to build sophisticated web applications for other people, i.e. customers.

Nielsen's dogma was excellent for the latter, and disastrous for the former.

History has been kind to Nielsen in the way that the modern web has lost most/all of its charm for the sake of answering the question "but how does it make money?"
