All my university systems run on Microsoft. All my future employers' systems will probably run on Microsoft. All public transport in my country effectively requires an app which is tied to either Google or Apple operating systems to buy tickets. Schools require students as young as 6 years old to have an iPad or chromebook tied to Google or Apple.

There is no real choice in our modern society to "not give your personal data" to these megacorps.
