They were already colluding. At least now workers can see it and form unions to fight back.

Except if one chooses not to play ball and pay a little more, it can have the best of the pool. So others compete, I think that's how this is supposed to work

They share it amongst themselves via third party consulting firms already. This just gives the public visibility.

We just gave "big data" more "big data". They surely won't use it against us!

then no one will work if they can choose to not.
