Yes, we'd have to be naive to think that this won't be a huge issue. I can only imagine what's going to happen when places like law firms and medical practices realize that Microsoft's turned on the data siphoning without telling them.

For normal users I always advise installing something like AME, for example AtlasOS's AME. Which will disable all the telemetry as well as updating (so it can't auto-reinstall). It does mean that you have to reinstall windows to add updates but that's a consequence of linking the telemetry and update systems together.

I still remember back when online security updates first started taking off and Microsoft absolutely assured people that the updates would only ever be used for security fixes and absolutely nothing else, while implying that it was just paranoia to think otherwise.
