Why was the "tug-of-war" event removed from the Olympic Games?

Tug-of-war was dropped from the Olympic program after Antwerp 1920, presumably due to the number of controversies. At London 1908 the American team protested its first round loss to the Liverpool Police, claiming that the Liverpudlians were wearing illegal boots. When the Liverpool team challenged the United States to a re-match without shoes, there was no response from the Americans, who withdrew their team comprised of athletes competing in other events.

At Stockholm 1912 the British team lost the first pull of the final to Sweden and was then disqualified for continually sitting down.

The English Tug of War Associations states that it was merely because of an overabundance of disciplines. No word about controversies:

After the 1920 Games, Tug of War was removed from the Olympic Programme along with 33 other sports. During this time, the IOC decided their were too many sports and too many participants competing, so took the decision to remove a number of sports, and unfortunately, one of those was tug of war.
