If you think that what was being referred to as "Aikibudo" in that article was much of anything like what was in the video you posted, you are delusional.
The issue is combat vs pacifism. The combat elements from the original Aikido have been removed.
Neither Takeda, nor Ueshiba, INTENDED for Ueshiba's art to have a new name. AIKIDO was imposed by the Dai Nippon Butokukai and accepted by Ueshiba's representative there, MINORU HIRAI Sensei. From then on, the former Aikibudo of Ueshiba changed its name to Aikido and included also the kyu/dan ranking sponsored by the Butokukai.
O-Sensei's religious beliefs also contributed in important ways to the art he developed. O-Sensei joined the religious group Omotokyo in 1919, and he borrowed heavily from its philosophy and world-view as spiritual underpinnings for his martial art. To emphasize this, the changed the name of the art from Aikibudo ("the warrior's path of harmony") to Aikido ("the path of harmony") in 1942.
