Depends on your own morality, of course, but let's say you believe coercion and fraud are immoral. I could see one making an argument that fraud is in play, because the app users don't understand how their data is used. But contract law doesn't provide good protection for uneducated parties.
I'd say yes. Definitely evil. But not causing enough harm to warrant an intervention by the justice system. At least European lawmakers have attempted to enable avenues for justice to take hold, but it's pretty ineffective.
I guess you could also argue an oligopoly situation (coercive in nature), which would introduce all sorts of regulation and government oversight, which rarely does any good. Not to fault oversight agencies, but they're tasked with the nearly-impossible.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
