I think this is the entire problem. Crawford's first idea for answering the question is, "I'm going to read the book back to you." Then if he thinks that answers the question, he stops. The last thing I want for D&D, a game where there is explicitly a referee at the table to make decisions and alter the game, is a strict constructionist reading of the rules.
I'm not really interested in another pair of eyes reading the book when I take the step of asking WotC or Crawford a D&D question. I'm pretty good at reading comprehension (when I take the time to do it). What I want to hear is, "What did you mean when you wrote this?" or "What was the intended interaction here? Was this interaction identified even?" That's much more informative because it tells me what parts of the text can be ignored.
I would be much, much happier with a response like, "We didn't consider that particular interaction." I suppose in those instances it's not really helpful to say that. And people don't want to think. They want an answer. Maybe that's the problem.
Reminds me of G'Kar's sermon about God and truth. His first answer is deep and meaningful and thoughtful. His second is shallow and empty and cliched. And his followers prefer the second answer.
Crawford knows those of us who can decide what to do don't need Sage Advice. He also knows that there are a ton of people who don't want to know that there's a man behind the curtain who, truthfully, wants you to think for yourself and join the former group. But those people don't want that. They want an answer they can quote, chapter and verse. Maybe that's all he's doing.
