I found a few articles on why EA delisted the titles. Unfortunately, they don't
actually explain why they delisted the titles.

"When making decisions that affect players we take the time to review exactly what the potential impacts are and whether they serve the players' best interests," Bruzzo said. "When we delisted Syndicate and Ultima Underworld we missed that step and so didn't fully consider the players' perspective."
Why would these things need to be reviewed? Once in GOG's library what more would need to be done except let it sit and hope it makes money. Once available, it doesn't cost EA anything to maintain a presence there, right?
