I posted on this controversy a while ago, and now thanks to Kieren McKenzie, have been sent a link of an interview with Aldo Gonzalez, the Indigenous Rights Officer of Union of Social Organizations of the Sierra Juarez of Oaxaca (UNOSJO).
The geographers' sin in this case seems to be one of omission by not informing Indigenous participants of one of the studies sponsors - Radiance Technologies - a company that specializes in arms development and military intelligence. Resulting and data was also hoovered up by Human Terrain System, a United States Army unit, for their global database that forms an integral part of the US counterinsurgency strategy.
Serious teko comrades.
Anyways, like Kieren says, all maps are liars so best we geographer always tell the truth.
