GitHub official CLI released, overlapping with GitHub employee's CLI “hub”

«In weighing different possibilities, we decided to start fresh without the constraints [cut] that hub can be safely aliased to git.»

Uh, that is definitely "embrace, extend, extinguish".

The official github client, hub, was 100% compatible with git and offered additional feature (embrace, extend).

Now the official github client is not 100% compatible with git anymore (extinguish).
