Back in the 1960s there was, seemingly, a brief period of relaxation in authoritarianism among Jehovah's Witnesses. Those who have read Raymond Franz's 'crisis of conscience' will have heard the story about Dan Sydlik's remark about the need to 'open some windows to let some air in here'.
There is a little mismatch of time periods here, I think. There was a time period in the years '77-'81 where there was more open discussion, quoting Barnes Notes, other Bible Translations, etc. Sydlik's quote would have been in that time period, not the '60's. Then the lockdown came with the events Ray Franz describes in his book in '81-'83. That is my recollection anyway.
There hasn't been any period of relaxation of authoritarianism since then. But on the other hand, most of the JWs anymore don't care much about doctrine or study. When they get together now, there is no discussion of Bible, doctrine, or anything like it used to be. It's more of a social club now.
