There is also an important distinction to make when talking about this: as Redshell's spyware is a product, Redshell does not actually have control over what the buyers of that product can do. So, just because Redshell doesn't sell the information its spyware collects about it's users to third parties, that doesn't mean that the buyers of the product do not or will not sell the information that they collect through Redshell to third parties.
