AP says this at the end of its birthday report:
Open discussion of the monarchy and its future is difficult, because a lese majeste law makes it easy to prosecute people who have been accused of insulting the king or royal family. If convicted, they can be sentenced to three to 15 years in jail. There have been dozens of such cases in recent years, with several people convicted and jailed.
It hardly needs reiterating but see the following and recall the huge efforts made for conformity (“unity”), including locking up political opponents:
