Here's one example why this is a bad decision. From a sailing forum [1]:

"I just read an article... that says that there will be no way to turn off updates on Windows 10. That's going to impact cruisers with limited access to the internet. Trying to download an important email? Please wait while we phone home to Microsoft first, then download 1.2GB of updates..."

Granted, if you have Pro, maybe it's not as much an issue because you can delay it for months. But I still think MS is making a bad decision in their attempt at control.
