And who would pay for the lawyers needed for such an action?
The recent dispute between Castle and ROL probably cost both companies lots of money in legal fees and lost business -such an action as you seem to be advocating would only cost more. Can any RISC OS company afford that, particularly on the chance that they may not win?
I agree with Moss, the new Acorn may not be morally correct in what there doing but are we so sure theres anything actually illegal in their actions?
RISC OS won't survive if our only defence is slagging off any competition. What we, i.e RISC OS users and RISC OS companies, need to do is show what RISC OS is and what it can do rather than rant about some company trading on past glories.
