Malaysia has had a history of religious discrimination from both the state and citizens, despite there being a freedom to practice whatever religion you want. Their notion of religious freedom is also strange, since in order to be considered a Malay you MUST be Muslim. And Malays get all sorts of additional rights and privileges (such as affirmative action). The country also has Sharia law courts - and this is a very real problem for personal freedom, because the Sharia court prevents Muslims from converting to other religions typically, and this forces people to have secret double lives, where privacy is critical.
Restrictions on Internet access or violations of privacy/anonymity are a serious problem for those who may run into trouble due to religious discrimination built into Malaysia’s culture and law. Do not accept official explanations like protecting people from harm or stopping misinformation - control over the internet will be abused.
