It's kind of weird (and worrying tbh) that the user doesn't get _all_ the data by default. Shouldn't all the data be sent upon request, is there a clause saying 'only after nagging the TRUE data will be sent?
There's a sense in which summary views are the real data. If I asked Spotify to share my data, and they just sent me a 250 MB file of every interaction they've ever recorded, I would conclude they're trying to obfuscate which data they actually use and how they use it.
