I'd be interested in whether this was related to Gaiman being that involved with production, or if there was viewership data that suggested it wouldn't sufficiently recover the costs of production and this was a convenient out.
I suspect if they thought it would be profitable enough they'd go ahead, considering their continued support of controversial figures.
Edit:
Skimmed the article, was just already planned to end with season 2 prior to allegations, so they didn't have a hand in it.
