Even without switching countries, without a VPN every app on your phone knows when you leave home (switch from residential IP in city x to mobile IP in city x), arrive at work (switch from mobile IP in city x to business connection IP in city x), or take a flight (switch from mobile IP in city x to mobile IP in city y), or drive far, or check in to a hotel, et c et c et c.

VPNs are essential for people who need to obscure their travel patterns from data brokers, for privacy or physical security reasons.

Blocking them is like making an app that doesn't work at all with location services disabled: it's a privacy-invasive dick move.
