Microsoft has always had a tendency to "not get it" on a grand scale, when it comes to stuff like this (advertising, social media, demo and marketing videos, etc.).

It goes back many years:

They're all pretty uncomfortable to watch, and are like a parody of someone trying to be funny.

However, I don't think Microsoft not getting it is sufficient reason for us to ignore them. They've done something really right somewhere along the way. I'm not sure exactly what it was, or if they're still doing it, but perhaps staring at it from multiple angles will help figure it out.
