I think the usual logic is that “everyone else is doing it”. And often they are right about that. For example, various forms of blood doping in top level cycling. The standards orgs running the competitions put more focus on arbitrary rules about the bicycles themselves than safety or doping, the latter is just a PR issue for them. So if you want to be “the best”, you either accept coming in 28th place naturally or top 5 doing what everyone else does.
