I was interested in this story and did some digging. I managed to find a WSJ article detailing it from 2000, but it was behind a paywall. I found another website duplicates the article

"A Year After Merger With Ameritech, SBC Still Hasn't Met FCC Conditions" https://www.barrons.com/articles/SB971041139934224266

I didn't look much for articles about when, if, or how SBC got out of these FCC requirements.
