Coming rather late to the debate; what surprised me was the tone of the Castle statement. Knowing the normal language and presentational style of Castle press releases, I was surprised to see words such as 'belligerence' 'intransigence' etc in the press release.
I hope that the concilliatory comments about the continuing supply of 26bit flavours of RISC OS bode well for the future as do the comments regarding new products from Castle.
Castle have invested lots of their own money into acquiring the RISC OS 'brand'. It is logical that they want to protect the brand name and take it forward in the future.
I don't see that the end of ROL means the end of RISC OS whatever version you happen to like the most.
