Hmmmm, usage of Google Public DNS or similar services is not always
decided by the individual. A lot of WiFi hotspots, hotels, schools,
even Internet access providers, configure the DHCP server to indicate
Cisco OpenDNS or another public resolver as the DNS resolver to use.

Also, applications talking directly to the DNS resolver, bypassing the
system-wide configuration was possible even before DoH.
