No, it's not. What you're proposing would be like the government saying you can only use this specific service, which may be run by the government, to communicate with others. Standardizing IM is making is so that if you want to talk to your friend across the country you're able to using different applications but the same protocol. Forcefully standardized would be mandating any messaging app that's used in the country would have to follow the protocol. It's almost the same thing that happened to fax machines in the 70s and 80s before the Japanese government stepped in.
