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".
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".
Honestly, I didn't even know there was a Remote Desktop app in the Microsoft store until they announced they were removing it. As long as the desktop app remains, I'm fine.
