for me it was all little steps during a longer peroid of time.
While growing up as JW, I never got inot serious trouble, but on the other hand , I never was fond of service, but I agreed, that it is important. What i never undertsood was reporting, didnt seem right anyway.
Later on, after learning aout 75, I was always disturbed, not that 75 happened as wrong prediction (false expectations excuse) but the fact, that the society long time never admitted their mistake, and blamed it on rank and file.
despite my little concerns I advanced to MS and later to an elder.
I considered myself always more liberal, and the point, that made me long time not really question the borg, was that sometimes the literatur seemed to be more balanced and open minded (in the 90`s mostly) than many elders in my old hall.
Just one example: even as teenager I never agreed and undertsood the no-beard rule we had in the hall, however, searching our litertur I enver found a clear prohibition of wearing a beard.
For a while, things in literatur seemed to move to a more liberal approach. i remember the Awake about pinatas, were it stated, that origin of customs alone does not matter, if today it is not connected to pagan things anymore.
I liked books like ´Daniel and revelation, because at least they offered something interesting without meddling into personal affairs of Christians.
But this course changed (at least my impression)
A few years ago, articles were published, with rules and regulations again (what is uncleannes, toasting is unchristian, gods love book etc). Also the blood doctrine sounded strange, the diffreence between fractions and components.
The tone at assemblies, as well as in some WT study articles seemed to become more condescending.
This all led to an uncomfortable feeling, partly with guilt and fear.
This i turn led to questions, which in turn led to research (particularly about blood), were I ended up at ajwrb.org, a webside I initially thought is from the HLC.
What I read there opened my eyes tremendously, next came jwn, and what was so surprising, not only beliefs I had doubts before, crumbled, but also many other things, i was sure of, were refuted with often much more convincing logic, than the WTs ever employed.
