Collusion is bad even for free markets (let alone other economic models), but rather than enter that lengthy argument, I'll point out one thing: they did this in secret. I'd be somewhat more understanding of your argument, if the companies had publicly declared they were colluding to keep wages down and prevent employee mobility amongst themselves. How do you figure prospective employees would have reacted to that?
