Yup, exactly. The only reason it didn't happen in Spain right away is the "inalienable right" clause, so that publisher's couldn't sign away the right to be paid. If that goes away, it'll be the same situation as Germany.
Now those imbeciles realize they shot themselves in the foot?
If they want Google to stay they should pay them. It's that simple
I'm guessing they analyzed the German situation as a failure of unity: some publishers "sold out" and signed no-money agreements with Google, which weakened the position of the holdouts. They -- possibly the same group of publishers lobbying for the German law -- presumably thought that if they forced unity, then Google would be forced to pay up rather than walk away.
