This is true, at least for international flights.
Unlike many other countries, the US and Canada don’t check your passport when you exit the country. That’s because the airlines give each government the passenger lists for each flight and it’s linked back to your entry.
Showing an ID card at the airport is about verifying the person getting on the plane has the same identity as on the reservation; it's not about being able to track you -- that's already done much more efficiently.
I agree there's a difference between intending to volunteer this info, but I'm pretty sure you have to use your legal name on your flight reservation in the USA, so the tracking is done whether you show your ID card at the airport or not.
