Googling suggests that solvent washing with ethyl acetate seems to be an extremely common method for decaffeination, and is usually done by industrial chemical facilities rather than by the coffee producers. Also, the swiss water method seems to be advertised as the "gentle" method rather than ethyl acetate which is obviously a much stronger solvent than water.
But I've only googled it for 5 minutes so I'm talking out of my arse of course.
