I've been on this forum for 12 years now. I faded a few years before that.
I've been pondering how the current crop of millennial ex-jws are different than the boomer/early-GenXers who left shortly after 1995.
I wasn't an "apostate" in the late 90s, but I do remember visiting the old H2O forum on two occasions. One was purely by accident as news had started trickling in of new GB appointments and I went online to confirm it. The second time was in connection with a search for the Creation book. That little blue book convinced me at 15 years old to forget my doubts and embrace the "truth" of the Bible.
During the few minutes I spent on that forum, I saw well thought out, lengthy debates about doctrine. Someone had gone through all the footnotes of the Creation book and pointed out how the quotes were misleading. There were echoes of that on this forum still when I joined 12 years ago, but the impression I got was that those debates had been thoroughly exhausted and were being brought up fresh as new arrivals discovered them. For the most part stuff like 607 BCE, blood, real WT history, had been settled.
But the JWs who were leaving and finding online forums in the late 90s were folks who were raised on Freddie Franz' ramblings and who were encouraged to do lengthy research into various WT doctrinal topics. Some folks fancied themselves JW scholars of sorts. It makes sense that a certain amount of reprogramming would need to take place in order to truly free yourself. I went through that lengthy process myself and it probably took a solid year or two.
However, if you go to the exjw subreddit today, which is full of millennial and post-millennial ex-jws, doctrine is hardly brought up. It's certainly not discussed as in depth as it used to be 15 years ago. I have to think that reflects the post '95 environment in the Witness world. The trend after '95 was steadily against "deep study" and more in favor of obeying for obedience's sake. There's no need to verify anything, just trust the governing body. People who grew up in that environment don't need the deep doctrinal deprogramming that I needed when I made my escape.
