Another horrible idea akin to anti adblock detection. VPNs are there for a reason and historically originate from corporate LANs needing to extend to executives' company devices. They're now mainstream and many millions of corporate devices will have all egress traffic routed through corp data centres that are by definition VPN endpoints, or cloud solutions like Palo Alto GlobalProtect. Have extreme caution using something like this.
