Depends on what you mean by "investigative journalism". If you mean, "ask questions and find out things", then yes, I like to think drobe.co.uk does. We do try our best, you know. Alternatively, if you mean, "try to dig dirt and cause mischief to get extra hits", then no. Sorry.
Anyway, having read the GPL and consulted others (like we usually do), we're certain CTL are conforming to section 3, specifically part b. They produced an announcement stating that the source is available from them if you send them a disc and we're mirroring a copy online if you're worried about availability.
Of course, one would assume that a copy of the aforementioned announcement is included with shipped Iyonixes. We can find out after the weekend I guess.
