I don't know how organizations are running Windows 10 with all the information Microsoft is getting from the OS. I checked with the resource monitor and even Explorer.exe is opening network connections beyond my company.
Depends on your organization. If you're government, the possibility of the government spying on your data isn't shockingly worrisome. A lot of types of businesses also would have no reason to care about privacy concerns, where a lot of reporting and accountability is already required, or where there's almost no contention for need for privacy.
Depends what branch of government, I suppose. For the NSA, sure. For anyone who works where most data is public or FOIA-able... I guess your biggest concern would be if Microsoft's spying managed to compromise the security of the network itself, which one would hope Microsoft is supremely motivated to not do, because they want you to use their products.
Nor am I confusing Microsoft with the government, but merely recognizing that in a backdoor model, the most interested party is probably the government.
> you seem to be confusing Microsoft with "the government"
Actually, thanks to the third party doctrine and the regularity with which the government subpoenas tech companies, there is little functional difference - they are part of the spying apparatus.
