Hopefully this is enough for some companies that insert obnoxious advertising into the WP dashboard to quit and/or make their ads slightly less obtrusive. The fact that someone felt that spending time to implement this plugin means that a significant number of folks are annoyed at this abuse (this isn't the only plugin that seeks to minimized the disruption of annoying WP dashboard msgs).

On a related note, I would LOVE for someone to create a plugin that disables animated icons in the WP dashboard. Some companies have decided that they want their plugin icons to scream "HEY, look at me!" by animating them. The animation serves no useful purpose and needs to either be prohibited by WordPress itself or a plugin created to prevent icon animation created.

"Make it and they will come..."
