I stopped subscribing to RISC OS World after a similar diatribe against Castle at the end of Version 8. I don't really care whether Castle/ROL are the goodies or the baddies (probably somewhere in the middle and depends entirely on your perspective). I took issue with the editor using it as a platform for such attacks without giving them a space to reply and so did not renew.
At the end of the day, RISCOS is an OS I use for both practical (its still a world-beater in many respects and a pleasure to use) and emotive (we grew up together) reasons and all this sadly undermines this. Even more sadly, it seems to be a general trend of the internet (you only need to hang around some Mac forums or slashdot to see similar).
