1.6% is 1.6% no matter how big the number is...
Personally, if my app were making 12 MILLION DOLLARS a year I'd either a) not care about that $200k a year or b) I'd then have the resources to do something about it
If I were these guys I'd support Spanish and French long before I'd bother chasing that 1.6%, but no one is being critical of them not doing that.
