In 1979, SIL's agreement was officially terminated by the Mexican government after critiques from anthropologists regarding the combination of education and missionary activities in indigenous communities, though SIL continued to be active in that country. At a conference of the Inter-American Indian Institute in Mérida, Yucatán, in November 1980, delegates denounced the Summer Institute of Linguistics, charging that it was using a scientific name to conceal its Protestant agenda and an alleged capitalist view that was alien to indigenous traditions. This led to the agreement with the Ecuadoran government being terminated in 1980, although a token presence remained. In the early 1990s, the Confederation of Indigenous Nationalities of Ecuador (CONAIE) demanded the expulsion of SIL from the country. SIL was also expelled from Brazil, Mexico, and Panama, and restricted in Colombia and Peru.
