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.
A specialized keyboard using different button layouts and settings per app. Also, not tracking keystrokes at all but rather "used special keyboard with app foo".
As a better example, suppose it were a game controller. Then the question "what games are people using this controller with?" seems quite reasonable. Filter to games only and anonymize the data and that would be fine.
