I found the response to be quite reasonable, and certainly not worrying.
Why would it be a good idea to ignore people that disagree with you? It seems like it would be better to provide rational counter arguments, in the hopes of starting a useful discussion.
I have used Redux on a few projects, largely due to the hype (I.e., good recommendations from others in the community) surrounding it. Without intending to I ran into several discussions on SO and Github where Dan explained why people may not need redux. I think this is a very nice thing, and I think it is unfair to blame Dan or other developers for not reining in the hype more.
I do agree that the title of the article is a bit alarmist and perhaps counter productive.
