Your ad placement and size has become obnoxious and intrusive. I know Yahoo has to make money by running ads. I understand that, but this is ridiculous. On the home page. In my email. Everywhere! Is Yahoo eventually going to become a full page ad on the homescreen where I have to somehow engage with the ad before I can get to the news articles and my email? I know you are also doing this to essentially force people to pay for Yahoo+. Ads are fine, but c'mon, just scale them back a bit. I am much more likely to look ad a well sized and placed ad if it is about something I am interested in than a billboard sized ad about the same product. Bigger isn't always better. But, in your case, more users will pay for no ads to avoid the hassle of having to scroll halfway down the page to get to the content they are looking for.
