I hate those things. They drastically reduce the viewable height of the actual content I'm trying to look at.

When I visit the Call of Duty Elite website there's a smart banner telling me to download the app. I went to the website because their iOS app is limited. When I click on the "x" to close it it takes me to the iOS app instead of removing the banner. I lose real estate like you mentioned. Real annoying.

The tell is the word "smart" in any branding term.

Agreed, but it is much better than most popups. Also its easily dismissed to reclaim the space.
