Google vice president Rahul Roy-Chowdhury wrote in a blog post that the company aims to keep the web healthy by "filtering out disruptive ad experiences."
But the company's motives and methods are both under attack. Along with Facebook, Google dominates the online-advertising market; together they accounted for over 63 percent of the $83 billion spent on U.S. digital ads last year, according to eMarketer. Google is also virtually synonymous with online search, and Chrome is the most popular browser on the web, with a roughly 60 percent market share .
