I think this is kind of flattening a range of different play. It's not hard to characterize playing, say, White Plume Mountain with reading from notes. Sure, the party sometimes has a few choices. They're all of a "go left or right" kind of nature. The storyline is not fixed, but it will consist of specific elements, the goal is set before play begins, and doesn't relate to the characters at all, etc. Sure, there may be outcomes of some situations that nobody planned, but the situations are either authored or the elements of them are. I think it is fair to characterize that as @pemerton does.
I was taking more issue with the confusion of the analogy

But if you are militant in how you talk about these things, people are going to react with militancy. And you can think you are right, but if you are dismissive of other peoples ideas about games, they will get angry and defend their techniques, their style, etc, perhaps even with a degree of hostility
