I don't think this is true. Based on the interviews I've read and the questions I directly asked myself over the years to people like Skip, the original team of Skip Williams, Monte Cook, and Rich Baker were brought in because they all had differing levels of what they wanted in the game, and Peter and Bill thought having a varied team would result in a great game what wasn't harmed by an echo chamber of designers. It wasn't a reaction against 2e at all, but a more generic new approach because WotC just bought the company. In fact, the original intent was just to make minor rules changes and clarity issues from 2e. Monte was actually surprised at how many of his new ideas were embraced and integrated. Not because they were meant to go against 2e, but because people thought they were a good idea. Not Skip, Monte, Rich, Jonathan Tweet, or Bill Slavicsek have ever told me 3e was a reaction against 2e, and I'm not aware of them telling anyone else that. Rather it seems 3e's big changes away from 2e had to do with people liking Monte's during the design process ideas and not as an active choice to be anti-2e.
The only move WotC thought about that was against 2e was to limit how many books were produced.
