A Wacom tablet is not the same as a phone, it is a peripheral. This is like your Dell keyboard tracking your keystrokes and what application they go into.

It's downvoted mostly because bringing up iOS and Android in a discussion about Wacom tablets seems pretty off-topic and whataboutist.

Because it’s like saying “well iOS/Android knows your contacts, so what’s the issue with Wacom siphoning your contacts?”

> How do I know that data doesn’t go back to Apple with “telemetry”?

By checking the privacy policy. Also, you can opt out of telemetry on iOS.

It's an attempt at technical whataboutism (alternately it's just confused and thinks a wacom tablet is comparable to an iPad or something). The operating system obvious has to know what apps you're running, and can store metrics to the same -- locally -- to improve your experience. There is no reason Wacom needs to know, much less share it externally. It adds zero value for the end user.
