Were they unable to sell the ads effectively? Was nobody clicking on them? Was the income not significant enough? Did they decide that it wasn't a good idea to have ads in Firefox? Did they find a better way to monetize the browser?
Anyway, the ridiculous content-free way this post is written does unfortunately not inspire confidence in Mozilla.
What does "value to the user" mean? What exactly were your goals for "value to the user" before you released the feature? How did you measure it? And how did you fall short of these goals?
People have even made games like Bullshit Bingo based on corporate-speak in meeting rooms. http://www.bullshitbingo.net/cards/bullshit/
Mozilla briefly dabbled with advertising on the new tab page. That's now stopping. Like the article says: "We have therefore made the decision to stop advertising in Firefox."
