The point of the report above is that you can NOT disable all telemetry, not even in the Enterprise version of Windows.
I don't for a second doubt you can turn it off completely. But unofficial solutions come with tons of potential issues.
Easier said than done when there's a minefield of firewall-bypasses for it.
So a whitelist method works, good, but I think it's fair to said that specifically blocking telemetry is extremely difficult with the way blacklisting works.
