Are you sure translation isn't a significant cost? Remember we are talking about simultaneous translation into hundreds of obscure languages here, not just one major language into another. A reduction in text of what, 50% in the last decade or so, must be a huge reduction in labour across all the branches involved. Plus the languages they removed altogether. I got the impression it was costly when the strange story broke about the house they bought in Wales as a supposed translation centre a few years ago. At the time they seemed intent on creating many such translation centres. I suppose that has been dropped in these straightened times.
Having said that, I suppose they will rely on computer translation at some point with minimal human input. It's becoming more and more reliable.
