Ok, so ROL's version of RISC OS doesn't have a HAL, doesn't have UDMA support, nor Gigabyte network support, lacks some of the USB facilities of RO5, can't handle PCI the list goes on and on. And you say Castle "stole" it from ROL. The version Castle have is a variant of 3.8 that was used by both Pace (who at the time OWNED RISC OS) and ROL (ROL's version later became RO4.XX and Pace's (later Castle's) became 5.0X).
ROL since 1999 have managed to produce a version of RISC that (apart from maybe CYMK sprites, round buttons and gradient backdrops) has changed little and is only fractionally closer to 32bit than it was then (when ROL committed themselves to produce a 32bit RISC OS). Pace (repeat PACE) owned RISC OS (lock stock and barell) and sold their rights to Castle - LIVE WITH IT and move on.
I am no lawyer but what you've written sounds very much like slander, perhaps next time you can publish your actual name so you can stand over your words eh ?
