To be clear, Spotify using my habits and data to improve their service I have no problem with; it makes a better service for me! Same with Apple.
Maybe I should have explained clearer in my original comment (though I thought it was obvious) but I have no problem dealing with companies that I deal with; it's companies I DONT have an arrangement with who I have trouble trusting they wont use my data against me.
And now it appears that Spotify is one of those companies. And all I want to do is stream my playlists on the way to work. Now I have to consider that they may be selling my contacts lists, movements, etc;
It's a plain cash grab at my expense. And I wont do business with businesses that don't respect me or my data.
