That maybe so. But then(assuming they are in the wrong here) they would be able to come a new unambigious agreement with Castle and after a short pause everything would return to normality with the air fully cleared. If Castle were unwilling to give ROL a license, there would be nothing stopping ROL from releasing their own feature pack for RISC OS which would sit on top of a standard ROM image.
