I've been personally involved in evaluating the security of a certain vendor starting with the letter H. Let us just say they are "less than honest". I had pcaps of their bullshit trying to reach out to random C2 shit on the internet, which garnered a response of "there must be a mistake, that is not our software".
Let China sell their telecom bullshit to all the poor people of the world - they will learn hard lessons.
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.
