I don't think you actually do understand what canon means in this context.

The argument is whether or not TMNT 2007 takes place in the same universe as the original live action trilogy, picking up where they left off a number of years later. That is what the film was intended to be, according to its writer/director, Kevin Munroe.

You say that it is canon, yet not a part of that universe. That's an oxymoron, it can't be both. It either is, or isn't directly tied to those movies (& it was supposed to be, whether or not we agree or like that notion).

You seem to think that canon means it simply exists, but of course it does, all TMNT iterations do. It's not a matter of discrediting it as being an official entry in TMNT history, the discussion is about its validity as a pseudo-sequel to a pre-existing series.
