      I think we can all agree that using some type of VPN, even if shady, is better than not using one. #RiskAcceptance is sometimes necessary in both Kim's & Tavis' example. There is inherent risk of attack/interception in anything, but esp. w/ WiFi.

      So who is keeping the list of shady VPNs? Google security researchers? Hmmm... I think not. You're doing more harm than good by telling users not to use VPNs. Tell them specifically not use "shady" VPNs, but I disagree w/ not telling them to use VPNs while on public WiFi at all.

      LOL, my jets are totally cool dude. Obviously, using a shady VPN is not smart. My point is that the average user doesn't know which VPNs are good to use or not. TLS is not perfect either, ever heard of ROBOT?

      As it happens, I have. That's of minor practical concern and doesn't work against most modern TLS implementations anyway.

      Right, but it serves to demonstrate that even TLS has vulnerabilities just as VPNs do. There is no perfect solution here. Public WiFi is shady as is, but as Tavis replied to me, "send your traffic wherever you want."

      Do you have any valuables in your house you want to keep safe? For $39.99 a month, I'll let you store them at my house. What's the flaw in this scheme?

      Let's agree to disagree. Let's also re-count the major benefits of VPNs shall we? 1. Encrypted tunnel browsing 2. Increased data privacy 3. Ability to visit blocked URLs depending on GEOLOC 4. Often faster https://goo.gl/N77aen  *free VPNs are not a good option for security

      3 is certainly true, but that is not a security concern. The other points are nonsense.

          Let me guess, using Chrome w/ TLS over public WiFi is the be all, end all? This is all quite comical. I can't even continue with this discussion... Agreed, total nonsense.

          Yep, using Chrome w/TLS (or any other modern browser) over WiFi is fine. I'm sure the fine people at http://hottechreviews.biz  haven't misled you though, and you should keep paying $39.99 to http://hidemyip.tk  for your "encrypted tunnel browsing".
