"Open source" is an established term, so CC rider in fact breaks it. Under CC-like conditions the source is accessible, as it is hackable, derivatives are permitted and they are usable. So it is technically "open" in a conventional sense of the word. There are however strings attached, so it's not free or libre. You can't do whatever you want with it, your freedoms are restricted. On the other hand, it is still more permissive than what's described as "shared source", because the latter doesn't usually allow for changes or even usage. So there's basically a distinct license category that lies between the "open source" and "shared source". There's no established name for it, but clumping it with "shared source" is not just.
