The sevarity is based on whatever the individual has done...and to what extent. Talking shit about another competitor is prety low on the totem pole...talking shit about an Official / judge is higher....making accusations of contest fixing is higher yet....competing in a rival organization...see ya later.
All depends on the 5 W's....
Lee is a high profile guy who jumped. That was damaging to the IFBB. No denying that. IFBB took some loss, even if we cannot measure it.
Some of the other guys did things like drugs or prostitution or pornography which - without argument - was a greater damage to SOCIETY.
Lee might have swayed a few sponsors to give their money to someone other than the IFBB promoters. And a few ticketbuyers might have skipped the NY Pro for the NOC. So yes, there was an impact.
Do they put a hgher value on damage done to their own firm, than damage done to society?
