When you are looking for a new Windows app, does opening up the store even cross your mind?
I nearly always go to a web search + download first. Or if it's something dev-centric I look at scoop or chocolatey. The Windows Store is far, far behind in my mindshare.
There are a few glimmers of hope though. Python has begun to distribute via the store which is cool. And the Linux distros available are helpful in some edge cases or for a quick dev environment.
