Because it wasn't a big deal at the time. It was only later when crybabies like mentzer and coe harked on about the 1980 contest being a fix because they didn't like Arnold.
Yes, controversy came out years later ,so it did the Encyclopedia (new edition) came out 1999....
However I have to correct myself ,Arnold only talks 1980 Mr.O in one page in his
Total Recall: My Unbelievably True Lifeanother gigantic book Which was released some 10 years ago .
See Arnold Run the movie by Roland Kickinger and Bodybuilding greatest MC Bob Chick, is mainly focused on 1980 mr.O ..
Arnold did not like the movie at all, as they did not mention his kids and role as loving father" ...and hated the attention given to 1980 mr.O "....... I hope one day he can seat down and open up about the whole October 4 1980 .
