I have the app installed on my phone. I have it installed because I want the $20 amazon. I don't know if I really "need" the $20 amazon but it is 100% passive once it is installed. You literally need to do nothing. Every month they send you $20. I would not uninstall it even given the privacy concerns.
If you guys are so concerned about it then create something that puts cash in my pocket. I'll gladly run whatever app you want on my phone if you pay me.
