Wikileaks: Microsoft speaks out against Open Source in Thailand

A view behind the curtain — this is what it looks like when the State Department helps to promote proprietary software. From a Wikileaks cable:

Microsoft-Thailand’s Corporate Affairs Director identified software copyrights as a big issue. On the one hand, he praised the Thai government (RTG) for strengthening its IPR enforcement and education efforts, and said Microsoft was “very pleased” that Thailand’s software piracy rate has decreased by two percent a year since 2006. On the other hand, he expressed concern over the RTG’s Creative Economy policy of promoting the “open source” software model over the “commercial source” model as a means to curb piracy.

I guess I’m confused. Wouldn’t promoting open source be an excellent way to combat piracy?
