Our observations are very different, but OK. What about small business with 5-10 employees? They definitely need VPN, especially in WFH era. And no, they don't have (money to buy) Cisco.
> In addition, there are a multitude of consumer wifi routers out there with VPN servers built into them.
Of course. When I got a new contract with ISP they installed shiny new router. Do you know what VPN server is builtin into that router? None. And that router installed to all clients of that ISP (one of few biggest ISP in my country)
If families had VPN's, then maybe hosting family home servers that can be securely connected to w/o dealing with NAT/DMZ/Port Forwarding, and the demand for non-centralized services would go up.
