This thread is the funniest I've read in a long time, I can't believe ROL are still around let alone making such ridiculous comments.
Given that Castle has licensced its RISC OS IPR for use in several Digital TV products worth many millions of pounds to the licencees, I'm quite certain Aaron would have immediately received some communications from these licencees lawyer's if anyone believed there was even a minute shred of evidence to support what he is claiming. Go figure.
In reality ROL's rights to use RISC OS are only those granted by its licence from Castle and even these are somewhat tenuous at best. If ROL are spoiling for a fight I'm sure these rights can easily be terminated again.
Aaron is making comments that could be seen as defamatory to the business of several large companies; he should be aware he is playing with fire!
