Yeah, kinda.
For anyone who wants to skip the article--which is really just a fluff piece interview with Salvatore--this is the rest of the quote.
“That’s been one of the toughest parts,” Salvatore told Polygon in a Zoom interview. “4th Edition D&D almost broke me, not because I didn’t like 4th Edition D&D. I’m not making any judgments – positive or negative – on any of the editions, but the changes were so sweeping.”
He tries to put things from the games into his books and it's hard to do when things change drastically, so he just sorta fudges it.
Like you said, it's been around for a while, so most of the actual dungeons have been picked clean and all we've really been left with over the last 30-40 years barely fit the legal definition!
