Noted the data boxes on the PWS page are smaller prior to log in. After login all the data boxes are larger. Firefox
This visual update is like many others done by other organizations. The info is broken down into "tiles" that often are made graphic. In this way, the tiles can rearrange themselves to fit the many sizes and aspect ratios of all the possible desktop, laptop, notebook and tablet screens out there, so a single site design can work on them all in a more automatic way. When you log in to WU and the ads disappear, the tiles enlarge to fit the available space.
The "dumbing down" isn't done to dumb things down. It's a result of the design consideration that the tiles should be readable on the smallest screens out there, so what can fit into them for all screens is therefore limited.
Try this experiment. Change your WU PWS page browser window from full screen to part-screen and then drag the right edge of the window left and right to make the window wider and narrower. Do it slowly, and you will see where the page display changes from 3 tiles wide to 2 tiles wide. On my "standard" old desktop screen, when the tiles get bigger, the square ones grow in both directions, but the rectangular map tile unfortunately does not grow vertically, leaving blank space below it.
I'm not defending this style (in fact I don't like it personally), but it is the trend and it's not just WU doing it.
