Our sport???
If this was a sport, we would had been run-rulled back in 2005-sh.
I also don't get your question. Exotos are massed produced just like most other diecast. Granted, their detail, fit and finish are above others, but they are still mass produced. Had they not been kicked of China, they would be enjoying the cheaper labor as others.
If "loosing ground" means loosing value to you, I would argue that Exotos have never had it as they themselves sell them for 30% of their MSRP. I have several Exotos and have never paid more than 25 cents on the dollar for them. Yes, some special liveries go for more money as dictated by supply/demand and favorability, yet the same model with another livery goes unsold for $98.
