That's one perspective, but mine (and others) is that putting a dividing line that creates an "RiD2003" designation is something that Hasbro didn't actually do, themselves. It's something you can do on the basis of evidence (and let me be clear, I'm not disputing any of the facts you're citing. Only that your interpretation is not the only one that can be drawn), but it's arbitrary. If we're saying it's an RiD figure (and specifically, a figure of RiD Scourge), you really don't have a leg to stand on to say that it isn't, and trying to tell us it's from a different RiD line is picking nits.
You say the RiD2001 line ended, wth a new RID line created in 2003. I say that the RiD2001 line was resuscitated in 2003. Who's to call me wrong? Surely there's more basis to say that the "new" 2003 line is simply a resuscitation of the 2001 line than there is to say that RiD2015 (which didn't even use the same logo) is....
