It doesn't really put the security of the site at risk anymore than other add ons to the site like the gallery etc. The problem was that a vulnerability was found in the chat room add on. It caused the site problems and I think an alternative paid for chat room was added for a while but removed when it needed to be paid for again. The bit about paying might not be accurate but the cost and lack of use caused it to be taken down in the end.
