So, Fitbit forced some kind of game on its users. It appears between data that the user actually cares about: stats.
When you try to remove the game, it warns you that you will quit (no one signed up for it) and that... "you will be removed"? Sounds ominous.
And then, of course, it pops up again. The only way to remove it is to click the game card, get a splash screen in your face, and press decline.
Companies, respect user choice. Do not pollute user data with your engagement metrics. If something is deleted, it should stay deleted.
