Looks like that's primarily geared towards Office 365 but at least one German government agency is looking into Linux and other options due to 10's (and 11's) nosy nature. 365 runs in "the cloud." It's true a number of hospitals here will not use 365 as this stores client information in the cloud violating HIPAA. I know someone at two such hospitals. One uses self-hosted office and the other LibreOffice.
Enterprise versions of the OS do less "reporting" but they still send data unless IT disables it completely in the imaging process. A long time good friend and guy I mentored works in IT at US Air Force Bases and they do just that.
There is NO cloud. It's just someone else's computer(s) with the power to do with your data what they choose. In addition, you're not in charge of your data's security, they are. Some cloud based services even hold it hostage if you don't pay the subscription fees. I had to use Office 365 at work as does my wife now. I haven't used Office on my personal computer for over 30 years. First it was WPS Office until it became as bloated and issue prone as office, now I use LibreOffice.
I turn off ALL telemetry and error reporting, app usage data and the like. I'm not beta testing new versions of Windows any more so there is zero need to send this data to MS. I haven't been a part of the Insider program in a very long time.
I turned something off that makes accessing answers-dot-micosoft-dot-com impossible. The connections fail. I'm utterly heartbroken. Really. :rolleyes: All the answers you find there are elsewhere and the answers there are most definitely filtered and censored. They can't very well allow users to post methods such as how to circumvent MS espionage and data collection or get around requirements such as TPM 2.0. I find far more useful answers on Stack Exchange, Windows Club, Windows 10 and 11 forum and SuperUser for example.
The only "cloud" based service I use is Google Drive and that's for sharing files with others, files I choose. I have an open source program for just about anything I'd do in the "cloud."
