no, it got banned because the powers thatb e got pissed off because it made them look ad on one of their mega projects:
"In his memoirs, Lee Kuan Yew recounted that as early as 1983, when he was still serving as Prime Minister, a proposal for the ban was brought up to him by the then Minister for National Development. Chewing gum was causing serious maintenance problems in high-rise public housing flats, with vandals disposing of spent gum in mailboxes, inside keyholes and even on elevator buttons. Chewing gum left on floors, stairways and pavements in public areas increased the cost of cleaning and damaged cleaning equipment. Gum stuck on the seats of public buses was also considered a problem. However, Lee thought that a ban would be "too drastic" and did not take action.
In 1987, the S $5 billion metro system, the Mass Rapid Transit (MRT), began operations. It was then the largest public project ever implemented in Singapore, and expectations were high. One of the champions of the project, Ong Teng Cheong, who later became the first democratically-elected President, declared,"... the MRT will usher in a new phase in Singapore's development and bring about a better life for all of us."
It was then reported that vandals had begun sticking chewing gum on the door sensors of MRT trains, preventing the door from functioning properly and causing disruption of train services. Such incidents were rare but costly and culprits were difficult to apprehend. In January 1992, Goh Chok Tong, who had just taken over as Prime Minister, decided on a ban. The restriction on the distribution of chewing gum was enacted in Singapore Statute Chapter 57, the Control of Manufacture Act, which also governs the restriction of alcohol and tobacco."
Nice to see their hijacking of somebody else's intellectual property is grounds for them to sue torrenters.
It would be interesting if there was a defence put up that the parody provisions should clearly not be in effect here, seeing as this works' primary purpose is for sexual arousal rather than comedic comment.
