Perhaps the more interesting question is why these companies feel the need to "explain" why they are collecting telemetry or "disclose" how the data is used

The software user has no means to verify the explanation or disclosure is accurate or complete. Once the data is transferred to the company then the user has no control over where it goes, who sees it or how it is used

When the company states "We use the data for X" it is not promising to use the data for X in the future, nor does it prevent the company, or one of its "business partners", from using the data additionally for something else besides X

Why "explain" the reason for collecting telemetry

Why "disclose" how the data is used

What does this accomplish
