From the article: "Open sourcing it without considering the impact this will cause to other companies using the operating system is pretty crap."
Why does the unnamed mystery source in the Drobe article assume that Castle wouldn't talk to any relevant third parties first? Meanwhile, would any company still using RISC OS today that will have its business influenced by open sourcing please raise their hand? Yes? Anyone? Anyone at all?
(Tumbleweeds roll past, only one hand is raised...)
RISC OS Limited will of course see an impact if the operating system source code were to be released to the public under some kind of licence(s), but not necessarily a negative one. Given this article, we don't know anything about the amount of source code either - it could be a long way from a complete operating system.
All in all, a disappointing article in my opinion - a small amount of fact from Jack, then a lot of inaccurate guesswork. For example, I can't speak for anyone else at Tematic, but I'm quite happy to state that as an ex-Tematic engineer, I'm not owed anything (well, not as far as I know!). Not that anybody bothered to do some research and, say, *ask me* about it before going to press. Sigh
