Turning Windows into spyware is working out very financially for MS, so doing so makes him an excellent CEO. Your personal feelings about the company's products are irrelevant; only their financial performance is important.
If you don't like the product, you're free to not buy it, and use something else. There are many alternatives.
Sorry, that's BS. You made a choice to work at a job that uses Windows. You could work someplace else.
At my job, I can't not use Linux. If I refuse to use Linux, I get fired, because all our work is done on that. Your job is exactly the same: they chose, for whatever reasons, to use Windows for their IT infrastructure. You chose to take that job. If not using Windows was important to you, you would have asked about this before taking the job, and declined, and looked for a job that uses the OS you prefer. There's tons of jobs out there that require using either Linux or Mac. There might even be a few still using z/OS.
Part of working at a real job is using whatever tools they require you to use. I don't care much for Confluence, but I use it because my company requires it.
