I don't think that's a good extrapolation. It cost a lot because of the momentum of the current status quo. If they changed the status quo and set different expectations of what will be permissible and not, it would not cost so much to maintain. It's like comparing refactoring vs rewriting. One is a semi continuous process the other is a periodic thing that takes a lot of work.
