I don't agree actually that is how it should or can work for everyone. Senior researchers produce good quality research, and they have a network of high quality peers built over decades. Both those are necessary for them to reach out and ask for feedback, and get genuine and high quality feedback.

Junior researchers don't have these typically. They also benefit more from anonymous feedback, which enables the reviewers to bluntly identify wrong or close to wrong results. So I think open journals should continue to exist. They fill an essential role in the scientific ecosystem.
