I think you make a valid point, but there's a difference between their sales pipeline and their actual product. These VPN providers are businesses, and they're trying to optimize their sales. What demographics are most interested in their products? How did they get there? Does Google Analytics (or Facebook, or similar) have profiles on people shopping for VPNs? Are there advertising patterns that could have better ROI for attracting users?
I'm not defending the ethics of major VPN providers -- they certainly don't all have stellar records -- but I would be surprised if any major SaaS company didn't track user behavior on their brochureware/sales pages.
