Yes, I also feel in many cases is not abuse but scam. For example, I bought a Muse Brain device just to discover that plain retrieving of EEG (not meditation or sleep options in the mobile app) metrics was a subscriber only option. So what are you selling Muse? Refrigerators?
I had that happen with a sleep tracker for Apple Watch. It was a few dollars for the app, but to actually view the data it tracked while you were asleep, you had to upgrade to the premium subscription. Fortunately it was easy enough to get a refund[1].
