I think one of the reasons some members feel betrayed by the Church is that they are either analytical by nature or emotional by nature - and they come to see the Church as the opposite.
Think about that a bit:
Someone who has developed a black and white view of Mormon history and finds that shattered by exposure to opposing and compelling accounts often reacts emotionally to that result - since black and white views tend to be more emotional than analytical. Such a person sees the Church as having been conniving and disingenuous - both of which, in that person's mind, are "analytical" attributes. So, an emotional person criticizes the Church for being analytical, if you will, and "hiding the truth" consciously and for purely selfish reasons. The "truth" (whatever it is) doesn't matter in such a situation, since the reaction is predominantly emotional.
Turn to someone who has a more nuanced, gray view. That is generally a result of being more analytical than emotional, and such a person often sees the Church as more subjective and emotional. This manifests itself in charges of hiding truth and covering up negative things (and even lying about stuff) consciously in order to feed the emotional attachment of the membership. The end result is a charge of anti-intellectualism - relying more on emotion than the intellect. Again, the "truth" (whatever that is) doesn't matter in such a situation, since the the reaction is based on a perceptual difference.
That happens all the time on various group blogs that are more critical than others, and it can be frustrating to see how blind most people are to that bias. My interactions over the years with certain people are a great example of this:
I drive them nuts, largely because I am both analytical and emotional - so it's hard for many people to categorize me and see "consistency" in my words. Especially with those who are emotional, they often see my analysis of their posts and comments initially as rejection or criticism - rather than simply as analysis. On the other hand, those who are more analytical often try to read between the lines to find nuance and deeper meaning - and I try to avoid such nuance and hidden meaning when I am writing in a public forum. Hence, those who are prone to nuance and analysis often misunderstand fairly simple statements by over-thinking things.
The fascinating thing is that anlaytical and emotional people can reach the same overall conclusion, but each person attributes the motivation behind it to a different genesis - whatever is the opposite of their own personality.
It's a natural way to justify rejecting others, by classifying others as different than one's self.
