Nobody is forbidding Myanmar to launch their own satellite. After all, the Chinese and the North Koreans pretty much do whatever they want up there as well. But if you cooperate with others to put something up there, it would be very unusual if you wouldn't have to compromise. This includes limits on what purposes the equipment can be used for. Actually, according to TA, it seems Myanmar's government hasn't quite decided what to do with the thing. It's probably quite low right now on their list of priorities. And the Japanese still have to consider whether to toss it out or not. After all, the thing is up there already (sunk cost fallacy and all that). It seems possible they can work something out.
