The title is misleading because the article focuses on using VPN providers to obfuscate traffic when this is one use case of VPN technologies. The gestalt types of VPN usage are:

* Remote Access VPN: Connect to resources on your corporate network. An example of this is you're in a coffee shop on holiday and need to access a corporate resource.

* Site-to-Site VPN: Connect networks on two sites together. An example of this is you're in a branch office and need to connect to a resource in HQ.

Note that VPN providers give you a limited Remote Access VPN to their network, which they control. They can do whatever they want to your now-decrypted traffic before they send it out to the internet. If you want to obfuscate your traffic, Tor is a better candidate.
