It simply is not possible to provide a quality service unless there is some kind of revenue stream. Free VPNs often beg the question about how they are paying for their network costs. Often that means they are either harvesting and reselling the very data you are trying to protect, or at the least have some other flaw such as advertising. Quality of service is also often left wanting, and speed/functionality impacted. NodeVPN offers true privacy without any sacrifice on the quality of your internet experience.
