This raises the question of why Zidisha is making these statements. To assume a developed-world business context excludes the possibility that these practices are accepted and commonplace in the markets Zidisha serves. I have no experience with those markets, but it's worth excluding this possibility before expressing distaste for these practices.
Consider the following plausible scenario: Zidisha performs research into the market and discovers that these practices and rates are acceptable. One can even imagine they are preferable to the status quo. The issue is that Zidisha as a company has to generate press and justify its business to a developed-world audience whose gut reaction to such practices would make the company look like a pack of usurers, when in fact they could very well be doing a lot of good.
To me, this communication seems a compromise response to this conflict: translate the numbers and practices as best you can into language and terms developed-world audiences understand. Perhaps the company took some liberties with labeling and conversions along the way, and if this is the case they would do well to be more conservative, but overall I give the benefit of the doubt that this communicate is the result of a tricky conflict of business environments rather than deception.
