This is clickbait. They will remove the Remote Desktop app from the Microsoft Store. They are not removing Remote Desktop Connection (mstsc.exe), which is what most people think of when they hear "Remote Desktop".
They have a terrible naming history.
Remote Desktop App is deprecated and gets replaced by Windows App but Remote Desktop Connections aren’t affected.
I just read the entire article being a bit confused and it wasn't until I read here that I realized that the name of the replacement application is "Windows App".
Why?!
theregister.com has similar relation to facts as The Onion but not as funny
