Please, this is not censorship. In fact, the usage of other languages is mentioned in the main article. If it were censorship, all matter pretaining to the other languages usage in Malaysia would be removed. In fact, in the first paragragh, there are SEVEN ways how to call Malaysia in various languages and scripts.

 The official language box can only have Malay because Malay is the only official language. Unlike India, South Africa, or Canada or Singapore of which their constitutions say there are more than one official language, Malaysian constitution explicitly says only Malay is the official language. Thus - only Malay in the official language box. Wikipedia's job is to spread information, not make new information. See WP:NOR.

 For usual convention, see Template_talk:Infobox_Country. For general rule of thumb on naming, see Wikipedia:Naming conventions (use English). In fact, if we were to follow WP's guideline tightly, the first paragragh SHOULDN'T list the other SIX languages/scripts. An implicit compromise was made earlier on this if you cared to check the page history. If you push this, it's likely that, according to WP:UE, all other languages will be removed, undoing the implicit compromise.

 And for precedence from other article, see Portal:Montreal/Discussions/English Names/Draft policy. Also, Wikipedia_talk:Language_policy. See also United States of America - no Spanish despite Spanish is the second most spoken language in the US. How about Indonesia? As for your precedence, could you point to any where the constitution says there's only one official language while there are many other major spoken languages that are included in the box?
