That is not it at all. The lawsuit claims (from what I read in the article) that the issue is before turning down an offer to advertise on the site for $300 a month, the company had a 4.5 star rating. Two days after the refusal, the company claims that six out of seven 5 star reviews were removed (by Yelp).

This is about being forced to pay to keep your good reviews, not about page views. The company is just saying that with a reduced rating they saw less traffic, which is to be expected.
