While I agree with you in general, I don't think this is a true statement. There's always going to be debate. And when solutions aren't even attempted I don't think you can say that it implies that the solution doesn't exist.
The risk to WTC, I think, isn't so much whining by a subset of consumers. Or even serious competitors leaving the brand. It's erosion of the entire Ironman brand due to the perception among the mainstream population that the brand is indelibly linked to doping. Sort of like CrossFit is to seemingly a large % of this forum.
Or WTC could just throw in the towel and call "hormone therapy" a "lifestyle choice for aging athletes" and promote it as part of the brand. I'd be OK as long as it was transparent - just change the rulebook and get on with life. Just test pros.
