No-one seems to have picked up the naive comment from page 1. Even if castle own the whole of RISC OS that doesn't mean they can do what they like with it. ROL paid over 100K for rights to RISC OS. That's money spent by the dealers by purchasing shares in ROL. I understand that some bought something like 5000 shares (ie costing them 5000 pounds). I believe Castle bought 500.
Those shares, that money, went into producing a future for RISC OS. RISC OS 4, Select, Adjust and work specific for specific hardware was the result. The work continues.
No matter who owns RISC OS they have to abide by the terms of the agreement/licence that RISC OS own as do ROL themselves and anyone producing RISC OS products for sale in the market defined in the agreement.
Castle say that ROL has breached the terms of that licence. ROL deny that.
ROL say that Castle had previously breached the terms of that licence. Castle deny at least one of those breaches.
Whatever is the case it is *not* true that Castle can do whatever they want with the bits of RISC OS that they own.
