The number of ordinary things that run over a VPN is enormous. My employer's entire remote setup depends on one. So does the connection between my parents' local pharmacy and its head office, as I found out last year when it broke.

'VPN' sounds exotic in a headline. In practice it's plumbing.

Also everyone on hotel or café Wi-Fi who was told by their IT department to switch it on. A decade of security advice has been 'use a VPN on public networks'.
