Yea, it's really shitty.
Enterprise folks don't have this problem because they use the WAIK (or whatever it's called now) to customize the installer.
Anyone can use it, and from what I've read, the Win10 generation of the kit is much easier to use than previous versions (which were pretty bad).
But yea, this stuff is awful.
Checkout things like WinDebloat, Privatezilla, Winaero Tweaker, and LoveWindowsAgain. There's some overlap between them (as they were built for different purposes), but they all pretty much kill telemetry at the service or installed level (as in remove the components providing telemetry).
Yea, it's BS you have to do this. And screw MS for this crap.
