You're getting upset about the wrong thing because you apparently believe that software proprietors can be trusted. Ultimately who would tell you that a particular variant of Windows allows you switch some privacy-busting feature off? The proprietor — the very party you can't trust to tell you the truth.
Structurally no proprietor is any different in this regard: they're all untrustworthy by default no matter what they tell you a feature is for, how to disable that feature, or whether you can trust them with your data. The free software movement has been saying this for decades. More recently, Windows Telemetry had a preference setting which meant nothing (any updates to which falls into the trap described above), and the underlying structural problem with proprietary software remained as-is including software you don't even know is running on a proprietary OS. Snowden also clued us all into how Apple, Microsoft, Google, and so many other businesses are "partners" with spy agencies. There's really no good reason for tech-literate people not to know better than to trust proprietary software and argue from the perspective that the proprietor should mistreat you a little less.
