Opposite view: Salary disclosure primarily destroys value for people with strong negotiating skills but who are not necessarily the best contenders for the actual job - especially when it comes to highly specialized tech jobs as many of them are introverts. It also enables work force diversity which is actually the best outcome for the company in the long run.
Salary disclosure is also a prerequisite for having a public discourse about equal pay and equal rights based on factual information. You might call that to: "gang up", but I certainly wouldn't.
Our daughters, girldfriends, mothers and sisters are all living breating people in our lives - maybe even the most important ones we have where as a company is just a thing. My own startups are just a piece of paper, a tax information number, an organizational construct, nothing more. I can create another one in 2-3 days. Close a company and if there's customer demand, another one will just spring to life and fill the gap. I might be sad and in debt for a while, but society at large will not even notice. It doesn't matter.
