As we've noted for a while, a VPN isn't some kind of magic bullet. While it might help you hide some of your online activity from snoopy governments, nosy ISPs, or a packet sniffing dudebro at the coffee shop, it's not some mystical panacea. Unfortunately, in the wake of seemingly endless privacy scandals and a federal apathy to any meaningful privacy rules of the road, many people have been flocking to VPNs without understanding that many VPNs are scams, poorly configured (making you less secure, not more), and that promises made about data retention are often hollow.

Ironically, many of the companies most responsible for our privacy problems have now jumped into the VPN business to capitalize on consumer worries they themselves helped create. Like Facebook, which, in the shadow of the Cambridge Analytica scandal, thought it might be a good idea to launch a VPN that pretends to protect consumers from online harm, but actually exists solely to track your behavior online when you're not visiting Facebook.
