Why did the U$.$ S$.$ government order discontinuation of free sharing of wage and salary information among organizations?

Too much erroneous information was regularly disseminated by individuals who were unqualified to conduct such surveys.

Individual organization's conducting their own surveys were infringing on the territory of trade associations and professional survey firms.

An uncontrolled variety of survey designs rendered most of the data that was gathered only marginally usable.

The open salary survey activity was adjudged illegal under existing anti$-$trust legislation.
