You know that for sure? I have read otherwise, do not remember where though.
The first one was from Tomiki himself who said that Ueshiba never asked him to leave the Aikikai nor asked him to stop teaching randori. Shodokan home page reference
The second one comes from Ueshiba's attitude in his youth. He did not mind other "testing" his Aikido and that is a competitive attitude.
So, yeah I do know for sure.
