My response was relating to an open salary company in general, but the process in the article takes it even further by having the employees themselves play a significant role in the decision-making.

If I consider myself a high performer, I don't want to have to justify my request relative to others at the company, or what they received, or what they used to win over other people to vote to give them more money that isn't theirs. That's going to put me in a position where I need to win a popularity contest, be around a while (to comment positively on others' raises), or wait a few more months so I don't look pushy and selfish to the entire company.

...because none of that matters if I just do an interview elsewhere and get what I want!
