If you ever read tech magazines or articles ALL advise you that "Technical release OSs" which Win10 is, are for evaluation and advisory purposes only to help Microsoft develop the OS.

Of course part of that process is to receive automatic feedback as how the system behaves. Nobody could manually transfer the amount of useful info generated.
Why anyone who objects to this process would want to install it is beyond me.

I have it because I'm part of the evaluation team, mind you there are tens of thousands of us, but I use a separate machine for it.

The updates are endless and some drivers simply don't work yet, so it's clearly not for every day use.

If you don't want info to be sent just set your firewall to restrict but that defeats the purpose of the excersise.
