Hey. Yea, I have heard of this tool. To my knowledge it just provides a GUI to enable/disable reg edits and group policies. Win 10 telemetry is somewhat more pervasive than this app is equipped to deal with.
The Federal Office for Information Security (German: Bundesamt für Sicherheit in der Informationstechnik, abbreviated as BSI) have written a report on how to mitigate telemetry on Windows 10 LTSB 1607 and are apparently working on a review for 1809. Under lab conditions, they used man in the middle attacks to identify telemetry vectors which originate from Event Time for Windows which are baked into the OS. I have translated their report and applied the recommended actions to build 1809, I will await their update and apply any further necessary patches.
As you point out, the lack of user control over updates on Windows Home/Pro etc nullify any advantage of disabling telemetry if privacy is your concern though I'm sure the decreased resource usage will be beneficial to many.
I can't recommended LTSB/LTSC enough though. No MS store, no cortana, no candy crush nonsense. Get the N edition and windows media player isn't even installed. RAM, CPU and disk usage is markedly reduced.
Read about the sisyphus project here.
Feel free to PM if you'd like more info/help on install etc.
