An examination of the screen in the article seems to show uploading enabled by default. There is a radio button where you can select uploads to be restricted to your local LAN, but if the screen has the default setting, then it shows internet uploads are enabled.
I just checked an updated Win 10 Pro computer. WUDO was set to on, but the "send updates to" button was checked for "PCs on my local network." I don't remember setting that, so it might be the default, or maybe the policy change did not affect my edition of Win 10 Pro.
