Try to use recognizable in-store footage of a person in a commercial advertisement without their consent and see what the lawyers say. It's not as clear-cut as you are making it out to be. You cannot just use photos or video of a person however you want without their consent.

Spotify is not making commercial advertisements showing all the raw data they have collected on you. Instead, they are probably doing things like aggregating data on their users and looking for trends.

It's more like watching security footage (or having machines watch it and let you know what they've observed) and then making decisions with that information.

That's because footage of them uses their image/likeness. If I used an amalgamation of all my customers it would be fine.
