I had the impression that the parent implied the situation was advantageous to both employees and companies yet in reality it's only advantageous to the companies.
It's nice that Buffer exposed their salaries publicly, but I strongly dislike how they use location-based salaries. If they aren't willing to pay US salaries to EU people, they will never get the best EU people. For an average EU salary you'll get an average EU developer.

I'd go further and say that GP's argument is wrong. Open and public salaries are good for everyone. Just look at buffer. https://open.buffer.com/transparent-salaries-and-formula/
