The section "Protect you from viruses and tracking" doesn't actually say anything about tracking. And VPNs can definitely protect against tracking, as long as you compartmentalize well enough.
I just read the article, and that 10 minutes of my life I will never get back. Just another example of a staff writer trying to justify their existence with meaningless content.
Some trackers would a notice a IP/Country change if cookies were already set. Pretty sure most tracking companies will have checks on VPN users. Block trackers, referrers and 3rd-party cookies all the time regardless.
Simple sage advice: use TOR bundle or Whonix behind your VPN and have the best of both worlds! Add VM's and other cool steps if you want but even a simple TBB behind a VPN is like magic, it really is!
