I'm sorry that you don't think the apology was good enough. One thing I've realized about apologies, is that most are done out of necessity. Most apologies may never make the offended feel 100% pleased. It's a fact of life.
When I see killers apologize and weep in court for what they did, for some----"I'm sorry" means nothing. Unless they were put to death themselves, the apologies are immaterial.
If Watchtower ever "apologized" just like the RCC, I'msure we'd hear how those weren't enough too. And maybe mere words could never make one feel better about the abuse they suffered----whether it was sincere or not----I dunno.
