Might as well complain about how we get free roads and fire services.
No one has accused roads and fire services of being free.
This is a good example, because a "freeway" is free at point of use, but obviously understood to not be free of construction and maintenance cost. It is called "freeway" because "free-to-drive-on highway" would be too wordy.

This is wrong. "Freeway" comes from free flow of traffic:
