I think the biggest thing was there was never the outside pressure to change the lore. You can almost feel the brakes slammed on after the famous "orcs and drow" column. What would be acceptable in 2016 was not in 2020. I think they had to find a way to change directions while speeding along the highway at full speed.Yeah, contradicting material within the edition is a bit of a bigger deal. It makes it harder to compartmentalize (which is my primary way of dealing with changes in the game I don't care for, and which has been increasingly more difficult in the last few years). Of course, being surrounded online by people who apparently love everything WotC's doing doesn't make it any easier.
Lots of legacy media has been facing this problem. Even Paizo has been tackling this. Everyone is finding where the path will go next. Will mistakes be made? Absolutely.
