Using vpn for anonymity is a relatively new usage of the technology. Typically vpn is/was used for remote access to corporate networks. Its popularity as a privacy tool may mislead many to think that's the only reason to use one.
To answer your question, the point of a VPN is to provide a secure end-to-end tunnel between two endpoints, that's it.
I'm quite curious to see how this plays out in regards to employees remotely accessing their corporate network because that's that's going to cause logistical, technical, and likely financial issues for most businesses.
Vpns have been around far longer than people have been widely using them for privacy reasons
