I recently watched the first 30 minutes of Mike Acton's 2014 talk, and while that portion of the talk wasn't about ECS specifically, it very much presented an absolutist perspective.
A lot of it also stems from what I call 'the hello world problem'. Very simple cases are brought up to sell you on the idea, but it's only in complex scenarios that you really learn the worth of something.
He spent quite a bit of time at the start of the talk defining the context w/i which he was talking. He used strong language but it was never absolutist.
