They don't accept them, not really.
Rutherfraud closed the heavenly gate without authority in the 1930s. That decision was made because the "facts" made it clear that the END was at hand. Oops!! Now we have a problem.
As the "Generation" slowly died off, it became clear that Boozerford was wrong. Who would claim the throne if there were no anointed left? Booze had witnessed first-hand what a schism could do to an organized religious/business model. Leaders were needed, theocratic leaders.
No more anointed, meant no more divinely appointed leaders, or FDS/GB as we would call them today. That meant there would be no ruling class and no sheep to rule over. Without "God" calling the shots, nobody but nobody, would follow the bat-shit crazy dictates of a cult. Mystical manipulation is key and for that reason, "anointed" must exist. The question remains: Who would qualify for that lofty position?
The WTBTS inc, is a corporation, a living entity with parasites hanging on for dear life. The existence of the Organization is all-important and eclipses everything else, and everyone else. Widows, Elderly, the poor, children, none of them matter to the Pharisees running the show. Only the Company matters. This means that only company men are accepted as "genuine anointed."
The 80s taught us that the WTBTS can and will DF any who oppose them. They DF'd a GB member for daring to have a conscience and attempting to clear the merchants from the temple, so to speak. They also DF'd people for being "right" when the Organization was wrong. Many were accused of being self-decievers and apostates for suggestion that the FDS was comprised of only anointed at HQ! LOL!!
All of this nonsense stems from fear, IMO. Fear of the world at large, fear of life, fear of losing control, which is an illusion. At any rate, power had to be consolidated, and Boozerford excelled at that. Once you hoard something like power, you don't give it to just anyone. You give scraps of it to those who hunger for it, those who will do anything for it. Brother Eccentric, who believes that helping orphans and widows is more important that filling out a service report, does not desire power. He doesn't want a position over others, he has nothing to lose by disagreeing with corporate policy. Therefore, he is a poor candidate for the GB, and a possible danger to the hierarchy.
The WTBTS had a challenge on its hands. How could it marginalized the all-important future rulers, without disrespecting them outright and showing its cards? They simply waited for them to die. As time passed they quietly slipped in concepts, like not maintaining a network of anointed. Then they printed articles stating that "anointed" don't know anything more than non-anointed, like non-anointed Elders. So, "evidently" the Holy Spirit doesn't actually teach anointed Xians like Jesus said.
This makes sense from the WTBTS's point of view, a cult who demands conformity above all else. Such conformity would be impossible if men and women felt empowered to stand up against HQ. The corruption that exists right now would not be possible, or not be centralized as it is now if individual Xians were speaking out and cleaning house. Then again, things could be worse. Can you imagine TOMO running his own congregation?!? ( SHUDDER....)
As it stands now, only the GB are genuine anointed. Sure, someone else might be, but only if they support the company policies 110%. When GB Helpers magically become GB members, no one will question it. If Sister Cat-Lady partakes and says, "The Org should stop soliciting funds.", she will find herself in a star-chamber hearing, faster than you can say, Meow-Mix."
We also have to consider the history of failed prophecies in the WTBTS. The decrease of anointed was last mentioned, at least to my knowledge, in the Special Talk, "Is It Later Than You Think?" It was mentioned that this decrease was one of the signs that we were in the Last Days. So now what? Does the WTBTS admit to another failed interpretation or wrong expectation? Or, do they continue their spin-doctoring ways, using passive-agressive tactics to lable every "anointed" but those at HQ as mentally and emotionally imbalanced?
