Sounds plausible. By far the plurality of complaints on that page have to do with the loss of customizability. It's as if Yahoo desperately wants people to flip through several pages of unrequested information from sports scores to stock quotes, where one custom page would have sufficed before.
This also ties in with the overall industry trend of using more pixels -- in the form of unnecessary whitespace and large fonts that, again, can't be customized by the user -- to display less information. Once again, the company gets more ad revenue as users struggle to access content that was previously displayed in a more compact format.
These days, beleaguered behemoths like Yahoo and Microsoft focus their business strategies on their wants and needs rather than those of their users. Obviously, this kind of abuse will only work until they're replaced by more customer-centric organizations.
