I think people should share their salaries. Yes there are differences in people that often drive different salaries. Regardless of how things end up, by sharing salaries, you promote discussion, it forces transparent and honest conversations which I believe there should be a lot more of. In the end, some people will make more than others etc., but at least the conversation is had, everyone understands (whether they agree or not).

Technically, by removing those items, maybe the are in fact being more 'honest' in the sense that they are letting everyone know they are not or can not be.
