Of course this could be abused, but so could many other features. A receiving client should give its user the option to not display such coloring - this is necessary for vision limitations, colour-blindness, and plain annoyance - but that's not a reason to throw away the feature entirely; I think it is a desirable feature for many users. For displaying coloured text on a badly contrasting background, e.g. white text on a white background, this can easily be handled intelligently by the receiving client: the client knows its own background colour, so if receiving white text it can either display this as light grey text or simply ignore the colouring entirely.
