We have published a tool called 'Do I need a VPN?' to help people decide if they would benefit from using a commercial VPN. If anyone you know is unsure whether they need one, we can help resolve their questions:
https://www.doineedavpn.com Do I need a VPN is open source. You can review the decision tree and all end states and submit issues on GitHub if you have improvements in mind.
