Sorry to say but its Genndy's words against your own.

Genndy confirmed that its a canon alternative to the series finale ending.

You can call it non-canon if you wish, but it doesn't change the fact that genndy himself confirmed otherwise.

Since its Word of God in this case, there is nothing you can really do to dispute it.

Unless Genndy refutes the claim (which is unlikely given that the game has been out for a while now and just about everyone has seen the ending for it) then the Game's ending is considered Canon to the overall story.
