Malaysian Government Prefers Open Code
The Malaysian gov't is happy to use OSS software if it saves them money. But any IT work done under a gov't of Malaysia contract cannot be released to anyone as it is protected by the Official Secrets Act (OSA).
Even if this OSA restriction didn't exist, the local IT vendors in Malaysia would never want the code they wrote to be under any form of scrutiny as their projects are usually failures that still result in big payouts for them.
Don't count on seeing a single contribution from Malaysia to the opensource community in the next couple of years.
