Ability to disable the "What's New Popup" advert

I found an old thread on the forums relating to this issue:

And while that is from about a year ago, it still keeps happening. I’m a WoW only player on the Battle.net side of things and in the past 2 weeks when I have logged on, I have received 3 unique adverts for Call Of Duty. I have similarly in the past when the old launcher design also had this happen, specifically for Call Of Duty every time there.

Just add a setting to control this obnoxious behavior, I don’t care if it is enabled by default or what, but an option to opt-out of this forced advertisement would be much appreciated.

Edit: Since my original post here it has happened 3 more times, like seriously.
