I think early in the '90s that was absolutely true. I dunno about running it at the table, but buying it? People were buying it!
By the end of the '90s? My impression, and one certainly supported by comments from various game designers of the era and I suspect by reviews from that era, if we go dig into them, people were pretty damn sick of it!
Also the Dark Sun adventure mentioned, Freedom made people mad even back in the day, I know that, but it might be because it was novel-based rather than the metaplot appearing through game products, which I think for some reason was better-accepted.
