While most users probably don't realize that they contribute to Wifi crowd sourcing, AFAIR using locations services is opt-in on iOS. So "without their consent" doesn't seem true. The info popup also explicitly mentions the WiFi location crowd sourcing.

Sure but any opt-in iOS user walking past other people's wifi is crowd sourcing those networks without the network operators consent.

Unless they only contribute networks that the device has authenticated with.
