I have no idea what you are referring to. Have you tried contacting these rumoured watchmakers you spoke of before, but they didn’t respond? If so, then that’s certainly not a good way to run a business.
As I’ve said clearly many times, Omega lets independent watchmakers be independent, something that would appear to contradict your imagined control they have over all of us. Watchmakers are free to run their business as they see fit, and sometimes that means they don’t do a great job on the business side of things. Why you are trying to tie this to them being certified by Omega or anyone else, well only you know that…
In the end, Omega still sells parts to certified independent watchmakers. That’s not as ideal as selling to everyone, but certainly a great deal more than most watch companies and large conglomerates do.
