This reminds me of the quip about conservative folks threatening to move to Canada because they're unhappy about all the corrupting liberal values creeping into American politics.
This isn't a line of reasoning that appeals to me but I can see how you might want to go this route if you've already compromised on security and privacy to get a shiny new iPhone.
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.
It is absolutely not.
Noun
cash grab (plural cash grabs)
1. (derogatory) product designed without love or care, with the sole intent of generating profits
2. (politics) Legislation that serves primarily the purpose of generating revenue.
3. An activity engaged in with the intention of making money quickly.
4. The money generated by a cash grab.
5. A game in which players attempt to grab as much money as possible.
What any REASONABLE person would assume is that Spotify is simply doing what everyone else does, which is track your usage of their product in order to better target ads.
The next "reasonable" thing to do is to let them use your phone's camera 24/7 to film your life so that they can get an actually good grasp of your consuming habits.
I'm hyperbolising here of course but this trend of using niche features like syncing your playlist's BPM to your pace as an excuse to track even more data and destroy your user's privacy must stop.
