For me there was a lot of red flags that started me thinking something is wrong here, but I never blamed the GB - it was the people not doing what we are supposed to. My wife had questioned stuff for years but we just put it in the "too hard" basket.
For me the July 15 2013 WT was what broke my trust in the GB. Then I started researching the scriptures and like Fayedunaway I saw how they changed the bible to suit themselves.
