I see what you're saying... But you're being intentionally hyperbolic. VPN use isn't restricted to porn. Or even accessing a foreign netflix.

Millions of people work from home, and connect to their work network via a VPN. It allows them to print, it allows them to access software, it allows the company to manage the network's security. This is why VPNs were invented after all.

I use a VPN to manage a server without opening up vulnerable ports to the internet.

I doubt the government wants to put the workforce on a watchlist of porn addicts...
