The thing that has potentially changed (if they can really pull it off) is the ability to get a reliable quote for any particular project in a few minutes. Any technical manager can duplicate the process of building out a project plan and lining up the cheap resources to get it done (and recruiting from schools or whatever), but being able to scope a project reliably, let alone estimate its cost, basically on the fly is a real challenge. If they've actually solved that, then this is awesome. If not, then it's probably just the same as paying someone to use ODesk (or Upwork or whatever they call it now) for you.
