It is kind of striking to me that in #328, there is a blurb at the end of the story saying that the next issue is the final issue of the series, but there's nothing whatsoever in the letter column. It kind of makes it seem like a bit of a surprise, you know? And in #329, when Gold does address the fact that it's the final issue, he takes pains to assure readers they have a great new relaunch being planned -- only the relaunch he talks about isn't by George Perez, it's by writer Greg Potter.
So it's very possible or even likely that Gold himself was being kept in the dark at least to a degree, and also possible that Newell is mixing up some details 30 years after the fact about a situation she was very clearly unhappy with.
Still, whether it was Gold himself or someone higher up, the way Crisis was handled in this particular series is pretty shoddy, and I gather form my still limited reading of other DC titles form the time that it was just about as badly handled everywhere else as well. A big damn mess for everyone involved.
