Sure, that’s true. AND some people who would have chosen a race purely for the ASI will now choose their race for role playing/story/just-because-they like it reasons, as I said. Our two statements are not mutually exclusive.

Sure. When 5e came out all the people who wrote 4e (and 3e?) guides wrote new ones, even though there is so much less to optimize. I doubt that will ever stop.
The question is how many, of the millions of people playing 5e, actually use those guides? But since both of us will be conjecturing, it’s not really worth discussing the answer.
