That question doesn't make any sense. Windows isn't used to run core network infrastructure on that level. These devices should never ever call out to remote servers unless explicitly configured to do so, and even then that should be a select list of customer defined servers.

Obviously Windows will send more telemetry if telemetry it sent at all, because it's doing more stuff. Then again, Window's telemetry is nothing compared to what Huawei phones will send to the mothership, and Huawei phones are nothing compared to an Amazon Alexa. Not that any of that is relevant.

I'm not comparing it to an OS. I'm comparing it to other competitors in the particular solution space. To answer your question: no one else's equipment behaved in that manner.
