I'm 10 years younger than you and have been out since the mid-00s. The sidelining of doctrine was inevitable.
One of the advantages we had was the general public's ignorance. We could soak up the fake wisdom and knowledge of the WT and feel like intellectual giants because the public was ill-prepared to provide a solid counterargument.
Looking back, I remember how big an impact on my faith it was to encounter the rare individual who'd studied Witness teachings and could push back. Being unable to easily dispatch them with a proof text was humiliating. Sure, I pushed it all back into the part of my brain where I shoved things I didn't want to voluntarily access again, but the impact was real.
Fast forward 20 years and more information than even those rare people possessed is available to anyone willing to spend 10 minutes reading the JW wikipedia page. Return visits would get derailed by having to respond to info the householder found online.
So instead of updating the doctrine, which is too hard to do, especially for a group run by a committee that requires a supermajority to act, you push doctrine to the sideline and make it all about the community.
The religion's appeal is much more limited that way. They'll manage to recruit emotionally vulnerable people who don't care about doctrinal consistency, but the real push is in retaining captive born-ins. But the walls are starting to crack there, too.
