Venezuela's Government Shifts to Open Source Software
According to government sources in Venezuela, the South American nation has announced an official policy that exclusively calls for the use of open source software in that government.
From the article: The announcement, made on Wednesday, stated that from now on, all software developed for the government must be licenced under the GPL.
You are right, whatever organizations are monitoring the Free Trade should be raising a stink over this. It's pretty much giving one OSS the potential to create a monopoly.
