Considering Flair was elsewhere in the earlier stages and doing the same type of conduct you can hardly blame a specific company.
it was probably wide spread across the territories. It’s highly likely that local promoters would sweep things under the carpet.
How ever one specific company did Aquire all of its competition. The only time that company has made changes, is when it has been forced to. Change number one was with the steroid trials, the 2nd was after The Crispen tragedy. Change number 3 could be Andrew Yangs push into their labor practises with the wrestlers being labeled ”Independent Contractors”.
so the reason people are pointing to one specific company, is 1. It is the last company of that era that is left. 2. Quite possibly the tall poppy syndrome. Lastly, the culture only changes when it has to, rather than wanting to.
