The decision to restrict access to the news site stemmed from its perceived failure to adequately adhere to a government-issued "correction instruction" related to an article published in May. Moreover, prior instances of similar measures by Singaporean authorities include the blocking of various media and civil society websites, such as those associated with the Malaysian NGO Lawyers for Liberty, the news outlet Singapore Herald, and the States Times Review.

The new license requires holders to take down content that breaches certain standards within 24 hours of being notified by the Singaporean government.

The Telecommunication (Dealers) Regulations apply to the import of telecom equipment for sale in Singapore. The scope of product coverage is defined under HS Code 8517, which includes telephone sets (including smartphones and other telephones for cellular or wireless networks), apparatus for the transmission or reception of voice, images, or data (both wired and wireless), and related components, excluding apparatus covered under headings 8443, 8525, 8527, or 8528. The import of telecom equipment for sale necessitates a Telecommunication Dealer's Licence issued by the Info-communications Media Development Authority (IMDA) and an import permit from Singapore Customs. Applications for these licences must be submitted prior to the import of such equipment. Both the Telecommunication Dealer's Licence and the import permit can generally be obtained immediately via online platforms, namely the TradeNet and GoBusiness Licensing portals. However, exceptions apply to specific categories, including Machine-to-Machine equipment, SMS SIM Boxes, and prohibited telecommunication equipment. Holders of a Telecommunication Dealer's Class Licence are permitted to trade only in registered telecommunications equipment or those specified in the First Schedule of the Telecommunications (Dealers) Regulations. The importation of prohibited telecommunications equipment, as listed in the Third Schedule of the Telecommunications (Dealers) Regulations (e.g., radio-frequency jammers, military-grade equipment), is strictly prohibited unless prior approval is granted by IMDA.
