What do you mean "nothing negative" has come of it?

It's also important to note that public employee salaries are within a specific domain with specific features. Among the most important: public agencies already have to publish pay schedules, so it's always been possible to guesstimate what someone makes given their job title. And there's the moral argument that citizens have a right to know how their tax dollars are spent.
